Re: When to use Z vs. E?
In most cases, I believe you use Z when it is "cis" (which means on the same side) and use E when it is "trans"(which means on opposite sides). Hope that helps!

Reaction Profiles
When drawing a reaction profile, what determines whether the products are higher/lower than the reactants?

Naming/Numbering Compounds
For a compound exhibiting both a triple bond, and a carbonyl functional group which one would get prioritized when numbering?

Re: Course reader pg 73 example
Yes you are correct! The 2 in front of the reaction constant is there because there are 2 NO2 formed. And yes, the intermediate is the product of the reaction for a fast step and is the reactant of the slow step.

Re: Post All Chemistry Jokes Here
In a sports relay race, a chemical kinetics specialist runs slowly, and his group loses the race.
When the chemical kinetics specialist is asked why he ran slowly, his reply was “I always wanted to be the significant rate determining step”.

For part b in this textbook question, why can we ignore C(gr) and Pt(s) when forming the half-reaction equations? Additionally, what is the purpose of those two elements?
Thanks!
Thanks!

Re: Change in internal energy= 0
One of the conditions when internal energy is zero is when the system has no temperature change, more specifically when the question says "isothermal".

Positional/Residual Entropy
In the textbook, problem 25, the n value the book uses is 6.02x10^23. I don't understand why Avagadro's number is used rather than a whole number, is this because the question says the arrangement is in "crystal form" or is it something else? (The n value I am referring to is from the Bolt...

Textbook Question [ENDORSED]
When we are calculating the standard enthalpy of formation and we are not given a net equation, how do we go about solving the problem? More specifically I am referring to question 8.65 from the textbook.

Re: Question about Enthalpy
I also had a question about enthalpy, will there ever be a scenario where we are solving for it but the pressure is not constant?
