The correct ascending order of adsorption of the following gases on the same mass of charcoal at the same temperature and pressure is

Options

A. `CH_4 lt H_2 lt SO_2`
B. `H_2 ltCH_4 lt SO_2`
C. `SO_2 lt CH_4 lt H_2`
D. `H_2 lt SO_2 lt CH_4`

Explanation

To determine the correct ascending order of adsorption of gases on charcoal, we need to consider the critical temperatures of the gases involved. The higher the critical temperature, the more gas can be adsorbed. Here’s a step-by-step solution:

### Step 1: Identify the Gases and Their Critical Temperatures
We need to find the critical temperatures of the gases in question. For this example, we will consider the following gases:
- Hydrogen (H₂)
- Methane (CH₄)
- Sulfur Dioxide (SO₂)
