$(A)$ $q=0$ $(B)$ $T_2=T_1$ $(C)$ $P_2 V_2=P_1 V_1$ $(D)$ $P_2 V_2^\gamma=P_1 V_1^\gamma$
$(I)$ ${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(l);$
$\Delta {H^o_{298\,K}} = - 285.9\,kJ\,mo{l^{ - 1}}$
$(II)$ ${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(g);$
$\Delta {H^o_{298\,K}} = - 241.8\,kJ\,mo{l^{ - 1}}$
