Re: Catalysts
In my understanding, if the initial step is slow, then the catalyst (intermediate) is included in the rate law.
If the slow step isn't the initial step, then you ignore intermediates.

Delta G naught vs. Delta G
What is the difference between these two? Also, how can we have different Delta G naught's at different temperatures?

Question 3 from Quiz 1
"Which molecule when a single crystal, would you predict to have a larger molar entropy at T=0K: SF6 or SF5CL? Why? (Both molecules have the same geometry with sulfur in the center)".
So according to the third law, should both have the same entropy of S=0 at T=0?
So according to the third law, should both have the same entropy of S=0 at T=0?

Re: Work is not a state function [ENDORSED]
Another way to look at this is graphically. If you take the graph of P and V, and you plot two points (final and initial), you can draw any amount of curves to connect these points. However, since work is the area under the curve of this graph, some curves will have a bigger area and some with a sma...

Change of State and energy
Since water can have different energies at different states, can we have a delta_H of formation for water that is at, for example, its sublimation point?
