Final answer:
The correct form of the Clausius-Clapeyron equation, which describes the relationship between vapor pressure and temperature, is ΔP/ΔT = ΔH/T (Option A).
Step-by-step explanation:
The temperature dependence of the vapor pressure of a condensed phase is described by the Clausius-Clapeyron equation, which is a fundamental equation in physical chemistry. The correct form of the equation relative to the options provided is A) ΔP/ΔT = ΔH/T, which indicates that the change in vapor pressure with respect to temperature (ΔP/ΔT) is equal to the enthalpy of vaporization (ΔH) divided by the temperature (T) times the vapor pressure (P). By understanding this equation, students can predict how the vapor pressure of a substance changes with temperature, which is essential in determining properties like the boiling point and heat of vaporization.
