Consider the following liquid-vapour equilibrium. \( \text{Liquid} \rightleftharpoons \text{Vapour} \) Which of the following relation is correct?

1. \( \frac{\mathrm{d}\ln P}{\mathrm{d}T} = \frac{-\Delta H_v}{T^2} \)
2. \( \frac{\mathrm{d}\ln P}{\mathrm{d}T} = \frac{\Delta H_v}{RT^2} \)
3. \( \frac{\mathrm{d}\ln G}{\mathrm{d}T} = \frac{\Delta H_v}{RT^2} \)
4. \( \frac{\mathrm{d}\ln P}{\mathrm{d}T} = \frac{-\Delta H_v}{RT} \)
