Consider the following liquid-vapour equilibrium.
Liquid $$\rightleftharpoons$$ Vapour
Which of the following relations is correct ?

$${{d\ln P} \over {d{T^2}}} = {{ - \Delta {H_v}} \over {{T^2}}}$$

$${{d\ln P} \over {dT}} = {{\Delta {H_v}} \over {R{T^2}}}$$

$${{d\ln G} \over {d{T^2}}} = {{\Delta {H_v}} \over {R{T^2}}}$$

$${{d\ln P} \over {dT}} = {{ - \Delta {H_v}} \over {RT}}$$
