AP Chem - Unit 9 Review - Thermodynamics & Electrochemistry in 10 Minutes

Показать описание

In this video, Mr. Krug reviews AP Chemistry Unit 9, which covers Thermodynamics and Electrochemistry. He includes a discussion of entropy and its calculations, thermodynamic favorability / spontaneous and nonspontaneous reactions, Gibbs Free Energy, kinetic control, as well as galvanic / voltaic cells, the Nernst Equation, and electrolysis calculations using Faraday's Law.
Note: At 1:34, there is a calculation error in the video. The correct entropy change should be +606.7 J/mol-K.

Like all the other comments here say: You are truly amazing!! Thank you so much for doing this. On that note, would it also be possible for you to make a separate video on how to effectively use a graphing calculator on the test? I've heard that knowing how to use a graphing calculator to its full advantage can actually decrease the test time by a lot. Thank you once again!

it's 1030 the night before my exam, ive been watching all of your unit videos, taking notes and refreshing myself on what we've learned, and this is so so helpful!! reminds me of all the major things ive learned w/o spending an unnecessary hour for one unit like other vids. Thanks!!!

JEREMY KRUG I LOVE YOU! Thank you so much for helping me get an A so far in Chemistry class!

Thank you so much for creating these ap chem videos! I have watched all the unit review videos and it had been very helpful for my review. I would like to point out a calculation mistake at 1:34. The final entropy calculation does not look right, and after I went through and calculated it, I got +606.7 J/molK.

One day left until the exam and these have been amazing for a quick review! Thank you so much!

Thank you for these videos! Gone through them all and they have been really helpful! It's nice to have short and concise reviews that are still useful. I've been getting discouraged by not doing so good on free response practices, but hopefully with more practice today and check backs to your videos, I can do a little better. Thanks again

Guess we'll see the results in a few months!
