Hey everyone,
I had a quick question. What are the units for the rate constant k for 0, 1st, and 2nd order reactions? I know each one is different, but I can't remember what they are.
Thank you and good luck tomorrow!!!

Functional Groups Naming (Priority?)
Hey everyone,
I had a quick question. When naming, do we give number priority to the functional groups? What happens if there are two or more functional groups? Which of those get priority? Also, if there is a double/triple bond and a functional group, which of those gets priority?
Thank you!

Re: drawing line structures
You can draw them in multiple ways and it doesn't matter how you start. Even if you start it horizontally or vertically, it's correct.

Re: Post All Chemistry Jokes Here
Two chemists go into a bar. The first one says "I think I'll have an H2O." The second one says "I think I'll have an H2O too" - and he died.

Kinetics Quiz
Hi! I was wondering how much of kinetics is going to be on the quiz next week? In the course reader, we didn't get passed page 73 (stopped before temperature), so will it appear on the quiz? Will the quiz only be problems similar to those in the homework that is before the temperature section or sho...

Balancing 14.5 part d
Hey everyone, I'm having trouble with chapter 14 question 5 part d. We have to balance the equation using half-reactions. The reaction occurs in a basic solution. We are given: P4(s) -> H2PO2-(aq) + PH3(g) In the solutions manual, PH3 is gone when doing it. I really don't understand how to the whole...

When to use which rate law?
Hi :)
I was just wondering how to know when to use either the differential rate law and when to use the integrated rate law? Why would you choose one over the other?
Thank you!

What is the relation between Gibbs free energy and electrochem? I don't understand why we can calculate G in this section.

Re: Entropy Chapter 9 #7
You would use basically the same formula for both parts of the question. For constant pressure, use: Delta S = n*Cp*ln(T2/T1), where Cp signifies a constant pressure. For constant volume, use: Delta S = n*Cv*ln(T2/T1), where Cv signifies a constant volume. Since it tells us we're dealing with ideal ...

Re: Textbook Problem 8.21
What you do is you set nC(Tf-Ti)=-nC(Tf-Ti). Now just be consistent with the grams and heat capacity copper and water by making sure they're on the same side of the equation. I personally did copper on the left side and water on the right (negative) side.

Re: -q(Rxn)=q(cal)? [ENDORSED]
In an isolated system, there is no transfer of heat or matter, so when you add up any and all the heat transfers, you need to get 0. So one is positive and one is negative in order to cancel out. So, you add the negative part to both sides. For example, 24 - 24 = 0. So add 24 to both sides and you g...

Steam Severe Burns Question
I understand that you have to add the ~41kJ and ~5kJ, but I'm not totally sure the actual process behind it. Is it because the steam has to change into water first? And if so, why does it have to turn into water to burn us?
Thanks :)
Thanks :)
