AI Generated Solution

To determine the value of ΔH_mixing for a solution that exhibits positive deviations from Raoult's law, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Raoult's Law**: Raoult's law states that the partial vapor pressure of each component in an ideal solution is directly proportional to its mole fraction. In ideal solutions, ΔH_mixing is zero. 2. **Identify Types of Solutions**: Solutions can be classified into ideal and non-ideal solutions. Non-ideal solutions can further be classified based on their mixing behavior: - Type 1: ΔH_mixing = 0 and ΔV_mixing ≠ 0 ...
