  4. T Nguyen says:

    Thank you very much for making these videos. These videos have assisted me very much.

  5. Ezra D says:

    Could you please cover organic chemistry, specifically the reactions of the Halogenoalkanes and Alcohols.

  6. winedragon says:

    Hell Yea, Just finished watching all your 71 videos in 42 Hours, great help man, now I'll just take the AP chem exam with only watching your videos , and will see how it goes 🙂 Big Thank You

  7. Ammar Khan says:

    Good luck in your AP tomorrow guys..

  14. kim y.j. says:

    Thanks for all excellent videos. Thank you Mister Anderson.

  15. Belugaman91 says:

    My AP Chemistry final is tomorrow, and my class never went fully in depth with relating Gibbs and equilibrium constant. As Equilibrium and Thermochem are the two biggest parts of the AP Chemistry exam, This video helped me put almost everything together, and helped answer almost all my questions for this year. Thank you SO much Mr. Anderson!

  16. Alice Zhang says:

    Thank you so much! Please keep making videos on other topics!

  17. blippetyblip says:

    Wow. I finished all the videos to help me prepare for the exam. It's been real, y'all.

  22. Jonny C says:

    I've learned this a few times before in high school chemistry, and college gen chem. Now I am in med school and we covered this as part of the intro into metabolism and the professor confused me more than I ever have before lol. Watched this and makes much better sense now. Thanks.

  23. Mostafa Karimi says:

    you're awsome man. thanks, for your videos

  24. Oscar Mendoza says:

    So awesome, thank you so much for all your videos! I do hope you make more!

  25. Eik Lin Oh says:

    you are so amazing

  26. MIMIC TUBER says:

    cleared my doubt

  27. Ben Richards says:

    Top notch!

  28. Emine Özen says:

    I know it's strange to say but I'm kind of sad that the series ended. Learning is much easier and more fun with Mr. Andersen. I hope he makes more Chemistry videos!

  29. Jim Shepich says:

    Thanks, Mr. Andersen! One fewer exam to be stressed about now.

  30. evita conway says:

    Really really useful and clear!! Thank you SO much

  31. jacob morris says:

    Paul you're a damn saint. Thank you for these videos because I feel so much more prepared for the AP chemistry exam than I did a few hours ago.

  32. Weston says:


  33. Phuong Thao says:

    Thank you so much mr.Anderson, it is awesome

  34. elaine Carter says:

    Thanks for posting this video. It has really helped me bring together several concepts for an overall better understanding of the relationship between Free energy and the Equilibrium Constant as it relates to chemical reactions.

  35. xCanko says:

    youre the best !

  36. cheyenne bolanos says:

    you're so amazing!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I love the visuals

  37. Rebecca Ruiz says:

    K>1 e>0

  38. Michelle Cheng says:

    Thank you Mr. Anderson! Your videos are really really helpful!
    I am going to watch them again and make some notes to review.

  39. Timoné Smith says:


  40. Inderjeet Singh says:

    it's very helpful to me,thx Sir

  41. safana Albayti says:

    thanks we hope to see in more videos

  42. Kiran Desai says:

    Mr. Andersen is one of the best teachers I've ever had and he's not even my real teacher lmao

  43. Evan Woodske says:

    I was good until he said at 5:51 that positive change in G was exergonic??? negative Gibbs free energy is exergonic…soo I don't understand the end

  44. J Pinho says:

    Amazing! Thanks!!

  45. Nashita Syeda says:


  46. Michael Berman says:

    Alex, I said MSG

  47. Bobby Dave says:

    I've watched all of 71 of these videos for review so thank you!

  48. OswegoIcebox says:

    This playlist is the entire thing I've used to study for the chem test tomorrow. Let's hope it works.

  49. Michael Sedrakyan says:

    I love this man!

  50. Grovhakket says:

    I love you dude!

  51. Minnie Raheem says:

    I'm from an Arabic country. I have a very important exam tomorrow and I didn't have anyone to explain what's Gibbs free energy or what's the chemical equilibrium . I watched all your videos about the thermodynamic system and the chemical equilibrium and you can't imagine how much you helped me to understand. I'm really thankful ❤

  52. Kevin Queally says:

    negative gibbs free energy does not always mean exothermic, and positive free energy doesnt mean endothermic. free energy and enthalpy are NOT the same.

  53. Sunita Banerjee says:

    Wow sir! It helped me a lot. Please keep making videos and I subscribed Now.. I really want videos sir!

  54. No this is Patrick says:

    This is a great video. Thanks for explaining it this way. I never had it explained like this and it is very useful

  55. Zayn Malik says:

    Thankyou this was great!

  56. Saliha Benkhaled says:

    Yes it was enormously helpful !

  57. roni champ says:

    fuck u Anderson love u

  58. kipling1957 says:

    You explained the link between these concepts well mathematically but not intuitively. How actually (at the physical/chemical level) can reactant/product concentrations affect delta G? E.g., is there some sort of modulation of entropy? I have no idea! Maths has never "explained" anything to me, just rules for a numbers game.

  59. Anu Singh says:

    SOO much more helpful than Rice University gen chem profs . Thank you so much

  60. Matthew Bang says:

    This guy knows everything. Thanks for the great bio and chem videos. Your bio videos helped me study to get an A+ in college honors bio!!

  61. 2030games says:

    Good luck on this year's AP Chem everyone!!! Anyone else here last minute??

  62. Rebecca Shan says:

    I have an AP Chemistry Exam tomorrow…..actually have a chance of passing it now that I've watched every single one of these amazing videos. Thank you for everything that you do.

  63. Fen says:

    Good luck on the AP exam tomorrow to those who watched this series.
    I have finished all 71 videos over the course of a few days.

    Will post the results… for science 😉

  64. Okabe Lintahlo says:

    Good luck to all of you who are taking the exam tomorrow, I think I'm looking to get a 4. If I remember, I'll reply with my score.

  65. Michael C says:

    Hi, I'm confused with the value of K, you mentioned the value of K can be neg or pos? I thought K = equilibrium constant can't never be a negative number rather it can be a very very small number but it'll still be positive (K<1). Please can you clarify this?

  66. Be You says:

    Perfect explaination…..u r a gud teacher bud🤘

  67. Kaylee Wong says:

    Thank you so much Mr. Andersen! I never comment on YouTube, but I want to truly thank you for all of your chemistry lessons. I watched every video in this series and learned more than I ever had in high school. You are a hero to all students with incompetent science teachers!

  68. Mark Davis says:

    Excellent series as are Professor Anderson's other works. If he is not a Professor he should be. Thanks for taking the time to make these very informative videos. Mark Davis, MD.

  69. leavesofgrass says:

    Watching this four years on and it's still SO beneficial. What a gift you have. Thank you.

  70. mpc greg says:

    thank you! yeah science! yes mr. A 🤓💯

  71. The geeky Pottercat says:

    You remind me of Sheldon

  72. Ward Vandenberghe says:

    Your videos have always helped in understanding these concepts. There's lots of video's, but for some reason I understand it best if you explain the concepts, a very big help! So thank you very much for making them 🙂

  73. Danielle Vargas says:

    Not all heroes wear capes… In this case they wear glasses and button-down plaid.

  74. Elvis Younes says:

    Thank you very much for all 71 of dem videos. Yes, it was helpful x71. 🙂

  75. catherine booth says:

    you saved my gpa!!!!!!!

  76. Kusal Uzumaki says:

    God bless you man

  77. Nick C says:

    AP Chem Test tomorrow after graduating a semester early from highschool, I feel soooo much ready now after watching all 71 videos and taking notes!!! If you guys find this series early on I'd recommend AT LEAST two weeks before the exam to bingewatch all of the videos and take good notes (and then if you want binge-watch all Crash Course Chemistry videos and do the same), then go to khan academy to do a bunch of practice and the day or two before the exam to re-watch the entire playlist again! Thank you Mr.Andersen you explained this a lot better than most teachers!
