Solution

(A) When $K_p > Q$, the reaction goes in forward direction, ie, the reaction is spontaneous. (B) Given, $\Delta G^{\circ} < R T \ln Q$, thus, $\Delta \mathrm{G}^{\circ}=+$ ve and hence, the reaction is nonspontaneous. (C) At equilibrium, $\mathrm{K}_{\mathrm{p}}=\mathrm{Q}$ (D) $\mathrm{T} > \frac{\Delta \mathrm{H}}{\Delta \mathrm{S}}$ or $\mathrm{T} \Delta \mathrm{S} > \Delta \mathrm{H}$ This condition is true for spontaneous endothermic reactions (as $\Delta G \geq \Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{S}$).
