Text Solution

AI Generated Solution

To understand why a solution of ethanol and cyclohexane shows positive deviation from Raoult's law, let's break down the explanation step by step. ### Step 1: Understanding Raoult's Law Raoult's law states that the vapor pressure of a solvent in a solution (P_A) is equal to the vapor pressure of the pure solvent (P°_A) multiplied by its mole fraction (X_A) in the solution: \[ P_A = P°_A \cdot X_A \] For a solution with two components A and B, the total vapor pressure (P_total) can be calculated as: \[ P_{total} = P_A + P_B = P°_A \cdot X_A + P°_B \cdot X_B \] ...
