The molar entropy of vaporization of acetic acid is `14.4 calK^(−1)mol^(−1)` at its boiling point 1`18^(@)C`. The latent heat of vaporization of acetic acid is:

Explanation

To find the latent heat of vaporization of acetic acid, we can use the relationship between molar entropy of vaporization and latent heat. Here’s a step-by-step solution:

### Step 1: Understand the relationship
From the second law of thermodynamics, the change in entropy (ΔS) during a phase change is given by the formula:
\[ \Delta S = \frac{\Delta H}{T} \]
where ΔH is the latent heat of vaporization and T is the absolute temperature in Kelvin.
