Question

Consider the following liquid - vapour equilibrium Liquid Vapour. Which of the following relations is correct?
  1. dlnGdT2=ΔHvRT2
  2. dlnPdT2=ΔHvT2
  3. dlnPdT=ΔHvRT
  4. dlnPdT=ΔHvRT2

A
dlnPdT2=ΔHvT2
B
dlnPdT=ΔHvRT
C
dlnPdT=ΔHvRT2
D
dlnGdT2=ΔHvRT2
Solution
Verified by Toppr

According to Clausius - Clapeyron's equation
d lnPdT=ΔHvRT2
According to this equation, the rate at which the natural logarithm of the vapor pressure of a liquid changes with temperature is determined by the molar enthalpy of vaporization of the liquid, the ideal gas constant, and the temperature of the system.
