We are asked to determine the Hvap for C6F6

We’re given a table of the vapor pressure at five different temperatures.

 Temperature (K ) Vapor Pressure (torr) 280.0 32.42 300.0 92.47 320.0 225.1 330.0 334.4 340.0 482.9

For this problem, we can use the Clausius-Clapeyron Equation:

where:

P1 = vapor pressure at T1

P2 = vapor pressure at T2

ΔHvap = heat of vaporization (in J/mol)

R = gas constant (8.314 J/mol•K)

T1 and T2 = temperature (in K).
