Determine heat of vaporization
WebExpert Answer. The compelete solutio …. Consider the heat of vaporization of toluene at its normal boiling point and at 120.0 °C. Trouton's Rule and Chen's Rule Estimate the heat of vaporization of toluene at its normal boiling point using Trouton's rule and Chen's rule and compare the results with a tabulated value of this quantity. WebLet's see. 4 times 200 is 800, 800 times 100; yeah, that's about right. Now, we're dealing with 100 degree water vapor, and we have to turn that 100 degree water vapor to 110 degree vapor. So we use the specific heat of vapor. 1.89 joules per gram Kelvin. Multiplied by the amount of vapor we're dealing with, 200 grams.
