If `P_(A)` is the vapour pressure of a pure liquid A and the mole fraction of A in the mixture of two liquids A and B is x, the parial vapour pressure of A is:

Options

A. `(1-x)P_(A)`
B. `xP_(A)`
C. `x/((1-x))P_(A)`
D. `(1-x)/xP_(A)`

Explanation

To find the partial vapor pressure of liquid A in a mixture of two liquids A and B, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Vapor Pressure**:
- Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid (or solid) phase at a given temperature. For a pure liquid A, this vapor pressure is denoted as \( P_A \).

2. **Identify Mole Fraction**:
...
