For this question, we have a chemical reaction of 2 moles, s .o .2 reacting with 1 mole oxygen gas.
00:06
We'll produce 2 moles of s .03.
00:09
And the delta h for the reaction is provided.
00:13
We see that we have 3 moles of gas going to 2 moles of gas.
00:17
So if the volume of the system were to be compressed at constant temperature, what change would occur? well, if we decrease the volume, it's going to have to shift to the side with fewer moles of gas that take up less less.
00:30
Space.
00:32
So it's going to shift to the right and as it shifts to the right we'll produce more so3 and we'll have less so2 and o2.
00:43
So the answer is the last one, shift to produce more so3.
00:50
Then for question 13 it asks which one of the following reactions would you expect to have the lowest delta s standard.
00:59
So the lowest delta s standard, so the lowest delta s standard, i assume that they mean the most negative.
01:10
That's what i'm guessing.
01:11
The most negative.
01:17
The most negative delta s occurs when we, well, we get a positive delta s when we make more moles of gas and we get a negative delta s when we make fewer moles of gas...
