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)
For this problem, we can use the Clausius-Clapeyron Equation:
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).
|Temperature (K )||Vapor Pressure (torr)|
By plotting these data in a suitable fashion, determine whether the Clausius-Clapeyron equation is obeyed. If it is obeyed, use your plot to determine Hvap for C6 F6.
