Sucrose $+$ $H _{2} O \rightleftharpoons$ Glucose $+$ Fructose
If the equilibrium constant $\left( K _{c}\right)$ is $2 \times 10^{13}$ at $300\, K$, the value of $\Delta_{ r } G^{\Theta}$ at the same temperature will be:
$(I)$ ${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(l);$
$\Delta {H^o_{298\,K}} = - 285.9\,kJ\,mo{l^{ - 1}}$
$(II)$ ${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(g);$
$\Delta {H^o_{298\,K}} = - 241.8\,kJ\,mo{l^{ - 1}}$
The molar enthalpy of vapourisation of water will be.....$kJ\,mol^{-1}$
