Question

Knowing the vapor pressure of water is 40.7kj/mol,calculate the vapor pressure of water at 58 degrees celsius

Answer 1

Answer:

the Clausius-Clapeyron equation we can estimate vapor at a different temperature.

The equation is

Δ

H

v

a

p

= Heat of vaporization of the liquid i.e. water = 40.7kJ/mol = 40700J/mol.

Let,P1 = vapour pressure at T1(58 degree celsius) temperature.

P2 = 1atm at T2=normal boiling point of water = 100 degree celsius.

Put these data in the above equation to find the vapor pressure at 58-degree celsius(P1).
