What are the values of `P_("total'")DeltaH,DeltaV` for negative deviation from ideality? Give one example.

Explanation

To solve the question regarding the values of \( P_{\text{total}} \), \( \Delta H \), and \( \Delta V \) for negative deviation from ideality, we will follow these steps:

### Step 1: Understanding Negative Deviation from Ideality
Negative deviation from ideality occurs when the total vapor pressure of a solution is less than what would be expected from Raoult's law. This indicates stronger interactions between the components of the solution than between the molecules of the pure components.

### Step 2: Analyzing \( P_{\text{total}} \)
For a solution showing negative deviation, the total vapor pressure \( P_{\text{total}} \) is given by:
\[
