Step 1

Step 1: We know that the entropy change for a reversible process at constant pressure and temperature is given by the formula: \[ \Delta S = \frac{\Delta H}{T} \] where $\Delta H$ is the heat of vaporization and $T$ is the temperature. Show more…

Key Concepts

Entropy Change

Entropy change is a measure of the change in disorder or randomness within a system when it undergoes a process. In thermodynamics, for phase changes such as vaporization, it is calculated using the relation ?S = q_rev/T, where q_rev is the reversible heat absorbed or released during the process and T is the absolute temperature.

Heat of Vaporization

The heat of vaporization is the amount of energy required to convert one mole of a liquid into vapor at constant temperature and pressure. It is a form of latent heat that is absorbed by the liquid during vaporization, and it is directly related to the entropy change of the substance.

Phase Transition

A phase transition is the transformation of a substance from one state of matter (such as liquid) to another (such as gas). During vaporization, the substance absorbs latent heat without a change in temperature, leading to a significant increase in molecular disorder and, consequently, in its entropy.
