Vedclass · Answer

(C) $1$. At $273 \ K$ and $1 \ atm$, the system $H_2O_{(s)} \rightleftharpoons H_2O_{(\ell)}$ is in equilibrium, so $\Delta G = 0$. Since melting is an endothermic process involving an increase in disorder, $\Delta S > 0$. Thus, statement $(A)$ is correct.$2$. According to Le Chatelier's principle, for the process $H_2O_{(s)} \rightleftharpoons H_2O_{(\ell)}$, the density of liquid water is greater than that of ice. Increasing pressure favors the side with higher density (liquid phase). Therefore, more ice will melt. Statement $(B)$ is correct.$3$. Since increasing pressure shifts the equilibrium towards the liquid phase, the melting point of ice decreases. Statement $(C)$ is correct and $(D)$ is incorrect.
