Clapeyron Equation deals with the____________________?
Correct answer: D. Rate of change of vapour pressure with temperature
- A. Temperature dependence of heat of phase transition
- B. Effect of an inert gas on vapour pressure
- C. Calculation of ΔF for spontaneous phase change
- D. Rate of change of vapour pressure with temperature
Explanation
The Clapeyron equation relates the slope of a phase-equilibrium curve to temperature, commonly expressed as the rate of change of saturation vapour pressure with temperature. It is based on latent heat and the change in molar volume during the phase transition.
