(A) The correct matches are: $(a)$ Entropy of vaporization is defined as $\frac{\Delta H_{vap}}{T_b}$ (Option $4$). $(b)$ For a spontaneous process,the equilibrium constant $K > 1$,which implies $\Delta G $(c)$ Crystalline solid state has the most ordered arrangement,thus it has minimum entropy (Option $3$). $(d)$ For adiabatic expansion of an ideal gas,$\Delta U = q + w$. Since $q = 0$,$\Delta U = w$. As the gas expands,work is done by the system,so $\Delta U$ decreases (Option $1$). Therefore,the correct sequence is $a-4, b-2, c-3, d-1$.
