`0.5 mol` of `H_(2)`, `SO_(2)`, and `CH_(4)` is kept in a container. A hole was made in the container. After `3 hours`, the order of partial pressure in the container will be

Options

A. `P_(SO_(2))gtP_(CH_(4))gtP_(H_(2))`
B. `P_(H_(2))gtP_(SO_(2))gtP_(CH_(4))`
C. `P_(CH_(4))gtP_(SO_(2))gtP_(H_(2))`
D. `P_(CH_(4))gtP_(H_(2))gtP_(SO_(2))`

Explanation

To determine the order of partial pressure of the gases \( H_2 \), \( SO_2 \), and \( CH_4 \) after 3 hours, we will follow these steps:

### Step 1: Identify the moles of each gas
We have:
- \( 0.5 \) mol of \( H_2 \)
- \( 0.5 \) mol of \( SO_2 \)
- \( 0.5 \) mol of \( CH_4 \)
