what is entropy of vapourization of water at 100 deg C, if molar heat of vapourization is 9710 cal/mol

Open in App

Solution

According to equation:

$∆ G = ∆ H - T ∆ S F o r a r e v e r s i b l e p r o c e s s, ∆ G = 0 S o, - ∆ H = - T ∆ S ∆ S = \frac{∆ H}{T} = \frac{9710 c a l / m o l}{100^{0} C} = 97.10 c a l / m o l /^{0} C$
