Consider the following liquid - vapour equilibrium.

$L i q u i d ⇌ V a p o u r$

Which of the following relations is correct?NEET 2016 (Phase 1)

Options:

Answer:

Solution:

$P = K e^{- ∆ H / R T}$

ln $P = \ln K - \frac{∆ H}{R T}$

$\frac{d}{d T} \ln P = \frac{∆ H_{υ}}{R T^{2}}$

$∴ \frac{d \ln P}{d T} = \frac{∆ H_{υ}}{R T^{2}}$
