Of `NH_3` and `N_2` which gas will be adsorbed more readily on the surface of charcoal and why?

Explanation

To determine which gas, \( \text{NH}_3 \) (ammonia) or \( \text{N}_2 \) (nitrogen), will be adsorbed more readily on the surface of charcoal, we can follow these steps:

### Step 1: Understand Adsorption
Adsorption is the process by which atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface. The extent of adsorption depends on various factors, including the nature of the adsorbate (the substance being adsorbed), the nature of the adsorbent (the surface), and the temperature.

### Step 2: Consider Critical Temperature
The critical temperature of a gas is the temperature above which it cannot be liquefied, regardless of the pressure applied. Gases with higher critical temperatures tend to have stronger intermolecular forces and are more likely to be adsorbed on surfaces.
