Answer #1

3. To solve this question, it's important that one is aware of the premise of Trouton's rule.

Trouton's rule says that a liquid that doesn't involve hydrogen bonding and has a boiling point of greater than 150 K would have a molar entropy of vaporization of 10.5 times the value of the gas constant.

The best examples of liquids that follow Trouton's rule are benzene and toluene.

Mathematically,

\small \Delta S =\frac{\Delta H_{vap}}{T_{b}}

\small \Delta 10.5 \times 8.314 JK^{-1}mol^{-1} =\frac{\Delta H_{vap}}{353.25 K}

\small \Delta H_{vap} = 30837.665 J mol^{-1} = 3.1 \times 10^{4} \, kJ mol^{-1}

Note: As per the regulation, a maximum of 1 question can be answered at a time.

    Phase transitions are similar to chemical reactions in that they each have an associated entropy change. A phase transition involves the breaking or forming of intermolecular attractive forces. A change in entropy accompanies not only a variation in the temperature, pressure, or volume of a system but also a physical transformation such as the fusion, vaporization, or transition from one crystalline state into another. In the equilibrium between two phases, the exchange of heat can be carried out reversibly, and...
