How do size of particles of adsorbent, pressure of gas, and prenvailing temperature influence the extent of adsorption of a gas on a solid?

Explanation

To answer the question regarding how the size of particles of adsorbent, pressure of gas, and prevailing temperature influence the extent of adsorption of a gas on a solid, we can break it down into three main factors:

### Step 1: Effect of Size of Particles of Adsorbent
- **Explanation**: The size of the adsorbent particles plays a crucial role in the extent of adsorption. Smaller particles have a larger surface area compared to larger particles. Since adsorption occurs on the surface, a larger surface area allows for more gas molecules to be adsorbed.
- **Conclusion**: Therefore, smaller adsorbent particles lead to a higher rate of adsorption due to the increased surface area available for the gas molecules to interact with.

### Step 2: Effect of Pressure of Gas
- **Explanation**: The adsorption process is influenced by the pressure of the gas. As the pressure increases, more gas molecules are available to collide with the surface of the solid adsorbent. This increase in collisions results in a higher number of gas molecules being adsorbed.
