Correct Answer:

Explanation

\begin{aligned} & \Delta \mathrm{G}=\Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{S} \\\\ & \mathrm{A}: \Delta \mathrm{G}\left(\mathrm{J} \mathrm{mol}^{-1}\right)=-25 \times 10^3+80 \times 300:-\mathrm{ve} \\\\ & \mathrm{B}: \Delta \mathrm{G}\left(\mathrm{J} \mathrm{mol}^{-1}\right)=-22 \times 10^3-40 \times 300:-\mathrm{ve} \\\\ & \mathrm{C}: \Delta \mathrm{G}\left(\mathrm{J} \mathrm{mol}^{-1}\right)=25 \times 10^3+300 \times 50:+\mathrm{ve} \\\\ & \mathrm{D}: \Delta \mathrm{G}\left(\mathrm{J} \mathrm{mol}^{-1}\right)=22 \times 10^3-20 \times 300:+\mathrm{ve} \end{aligned}
