Molar entropy of vaporization at normal boiling point in J/K·mole is:

Question

For reaction $A \rightleftharpoons B$, $\Delta G^{\circ} = 105 - 35 \log T$. Find the transition temperature (in $^{\circ} C$) of the above reaction at 1 bar.

Answer 1

Molar entropy of vaporization is calculated using $ \Delta S = \frac{\Delta H}{T} $. At their boiling points, most liquids have an approximate entropy of vaporization of $ 92 \, \text{J/K·mole} $.
