Question

Entropy of vaporization of water at 100 c if molar heat of vaporization is 9710

Answer 1

Vaporization of liquid leads to an increase in the degree of disorder or entropy. Entropy of vaporization is a measure of change in entropy during the process of vaporization. This entropy is positive. Entropy of vaporization ca be  calculated by the following formula.

Δ$S_{vap} =\frac{H_{vap} }{T}$

Molar heat of vaporization of water is 9710 cal/mol

Boiling point of water is 100 $^{0}$C =373K

Therefore Entropy of vaporization = $\frac{9710 cal/mol}{373K}$

                                                         =26.03 cal/mol/K
