ON the basic of data given above , predict which of the following gases shows least a dsorption on a definite amount of charcoal ?

Options

A. `CO_2`
B. `H_2`
C. `CH_4`
D. `SO_2`

Explanation

To determine which gas shows the least adsorption on a definite amount of charcoal based on the given critical temperatures, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Adsorption and Critical Temperature**:
- Adsorption is the process where gas molecules adhere to the surface of a solid (adsorbent), such as charcoal.
- The extent of adsorption is influenced by the critical temperature of the gas. Gases with lower critical temperatures are more easily liquefied and, therefore, are adsorbed more readily.
