A. Recall that molar entropies of solids and liquids are much smaller than those of gases, so
we can ignore the contributions of the solids and liquids to
when we order these reactions.
Considering only the gaseous products and reactants, we can find
for each reaction to be
a. b. c. The correct ordering of the reactions is therefore d.
