For the reaction, \( \mathrm{X}_{2} \mathrm{O}_{4}(l) \rightarrow 2 \mathrm{XO}_{2}(\mathrm{~g}) \),
\( \mathrm{P} \)
\( \Delta \mathrm{U}=2.1 \mathrm{kcal} \),
W
\( \Delta \mathrm{S}=20 \mathrm{cal} \mathrm{K}^{-1} \) at \( 300 \mathrm{~K} \).
Hence, \( \Delta \mathrm{G} \) is
(1) \( 2.7 \mathrm{kcal} \)
(2) \( -2.7 \mathrm{kcal} \)
(3) \( 9.3 \mathrm{kcal} \)
(4) \( -9.3 \mathrm{kcal} \)
