Hi, I just want to let you know that your videos have created my entire high school career success. You have guided me through Honors Geometry, Algebra, Chemistry, Physics, and AP Chemistry. I am so grateful to you for having posted such informative and thorough explanations on an expanse of topics. Please know that you are helping so many students and I hope your service grows to help even more. Thank you again.

I've been watching a ton of your other videos this whole week to study for my gen chem 2 final tomorrow. The way you explain things makes so much sense. I even noticed there's a difference in the way I approach problems now. Seriously thank you so much for this; you're amazing.

When I get to 13:29 and try to do the calculations I get an overflow error?

[@smokebonde9943]

3:34, when you say when products go up, and it shifts to the left, making E cell more negative, how come whenever you have a product-favored reaction, delta g is negative, but E cell is positive? I'm really confused. When you're describing the product-reactant relationships with the E cell, do you mean E naught or nonstandard E? Thank you.

[@ruu406]

Because delta g is equal to (-nF*delta E). Delta E is the non standard E of oxidator minus reductor. When it's more than 0 then delta G is less than zero. When that happens, the reaction runs spontaneously. The reactions that don't are electrolytic . Don't know if u still need this but yea

would it be the same thing to use log instead of ln, cause the other video i watched used log not ln, so that instead of raising it to e, we would raise it to 10 ?

from algebra they will be equal this way ( 2.303logQ = lnQ ), to avoid confusion use logQ formula if temp is at 25C. Any temp other than 25C use lnQ formula

[@parakhmody1413]

@The Organic Chemistry Tutor: E *can* equal E0 even when concentrations of participating reactants/products aren't all 1 M, right? Only the RATIO of concentrations of products to reactants (raised to the powers of their stoichiometric coefficients) must equal 1, ergo Q must equal 1. Perhaps, the definition of *standard* cell potential is incomplete and ought to be altered. Would appreciate a reply as I have an exam coming up.....
