The vapour pressure of pure benzene at `25^@C` is 640.0 mm Hg and vapour pressure of a solution of a solute in benzene is `25^@C` is 632.0 mm Hg. Find the freezing point of the solution if `k_f` for benzene is 5.12 K/m. `(T_("benzene")^@ = 5.5^@C)`

Explanation

To solve the problem step by step, we will follow the necessary calculations to find the freezing point of the solution.

### Step 1: Calculate the Relative Lowering of Vapor Pressure
The relative lowering of vapor pressure can be calculated using the formula:

\[ \text{Relative Lowering} = \frac{P_0 - P_s}{P_0} \]
