It asks for which process with delta H and delta G be expected to be most similar? I narrowed it down to either a or b during the test but then I got confused on the difference between them. The only thing I noticed was that option a was all in the solid state whereas option b had many different phases. Can someone explain why option a was correct in this problem and why options b,c,d would be incorrect
This is the way I did it, but I'm not quite sure if it is correct. So I used the equation ΔG°= ΔH- TΔS°. So for G and H to be equal, TΔS°=0. B, C, and D would be wrong because there is a pretty clear change in entropy for each one.
Essentially, this problem is asking for which equation would cause the least entropy so that G and H are similar. Entropy changes quite significantly when phases change, so the equation with the least entropy change would be the one with the solids on both sides.
