Answer 1

Answer #1

Clausius-Clapeyron equation

R In( ) vap-

∆Hvap the molar enthalpy of vaporization

T1 temperautre at one point

P1 corresponding vapor pressure at temperature T1

T2 temperature at another point

P2 corresponding vapor pressure at temperature T2

Substitute the value T1 = 358.0K, P1 = 26 torr

T2 = 429K, P2 = 392 torr

∆Hvap = 48796.976 J/mol = 48.78 kJ/mol
