The **Clausius-Clapeyron Equation** establishes a quantitative relationship between **vapor pressure** and **temperature**.

Where:

P is the vapor pressure of the species at temperature T

∆H_{vap} is the enthalpy of vaporization

R is the universal gas constant

T is the temperature in Kelvin

C is an integration constant

Suppose the vapor pressure of a substance is measured at two different temperatures.

By using the Clausius-Clapeyron equation, , derive the relationship between the vapor pressures, P_{1} and P_{2}, and the absolute temperatures at which they were measured, T_{1} and T_{2}.
