Calculations:

 

Calculate the heat of vaporization for both substances from the slope of the Clausius-Clapeyron plot:

 

Ethanol:

 

ΔHvap = -(slope)R

ΔHvap = -(-2260 K)(8.314    J    ) = 18,789.64 

                                       mol K                    mol

 

Acetone:

 

ΔHvap = -(slope)R

ΔHvap = -(-2100 K)(8.314    J    ) = 17,459.4
