When H and G are similar

[Jamie2002]

When given a set of reactions to choose from, how would we determine which ones would have the most similar delta H naught and delta G naught?

(Assume the deltas are in the following equations...)
G= H -TS
G=H when TS=0
When is S=0?
S is closest to 0 generally when x moles of solid go to x moles of solid. S is usually the most when x moles of solid/liquid go to kx moles of gas (a phase change occurs that increases entropy, k is some positive scalar of x).

Thank you so much!!
