Okay, calculate the gives free energy.
00:05
So the reaction is two moreths of the n -o reacts with one more -the -o -2, and we'll produce two mores of the n -o.
00:27
So the question actually gives the delta s and delta h, right? so in this case, we can first calculate the entropy and n -h.
00:51
N -lp of this reaction accordingly.
00:55
So the entropy, n -lp, right, equals to the formation n -lp, 2 times the n -lp of the n -o2 minus 2 times n -lp formation of the n -o -2.
01:09
Miners 2 times n -lp formation of the n -o minus, right, n -lp of formation of the o2.
01:18
So that's equal to, so, it's it's really confusing here.
01:41
So you'll find the m02 here is 33 .2, right? so it's 2 times 33 .2 minus 2 times 91 .3 .3 and minus 0.
02:07
So that's equal to about minus 116 .2, killed per more...
