Knowing that $\Delta$H_vap for water is 40.7 kJ/mol, calculate P_vap of water at 37°C.

Question

Quizplus · Accepted Answer

To calculate the vapor pressure of water at 37°C, we can use the Clausius-Clapeyron equation. Given the enthalpy of vaporization (ΔHvap) is 40.7 kJ/mol, and knowing the vapor pressure at a reference temperature (e.g., 100°C where P = 760 torr), we can estimate the vapor pressure at 37°C. The calculation shows that the vapor pressure is approximately 52.6 torr.
