The Claussius - Clapeyron equation is less exact than the Clapeyron equation due to its lack of exact differential in pressure and temperature, as highlighted by the integrating factor T-¹ Avap V₁.
Claussius - Clapeyron equation is considered less exact than the Clapeyron equation for phase equilibria involving the gas phase due to it not having the form of an exact differential in pressure (p) and temperature (T).
This lack of exactness is illustrated by the integrating factor T-¹ Avap V₁, emphasizing the differences in precision between the two equations.
Understanding these nuances in equations is crucial in the study of phase changes and thermodynamics.
