To better characterize your Valentine’s Day dinner wine, calculate ∆S for the following process involving ethanol:
1 mol CH3CH2OH(l), 25°C 1 mol CH3CH2OH(g), 100°C.
The boiling point of ethanol is 78.4°C.
Homework Answers
Entropy change of vaporization of one mole of ethanol = ∆Hvap/Tboil,
∆Hvap= 38.56kj /mol
= 38560/(273+78.4)
= 109.73 J/k is the entropy change for the process
