Atmolysis is a process of

Options

A. Atomising gas molecules
B. The breaking of atoms to sub-atomic particles
C. Separation of gases from their gaseous mixture
D. Changing of liquids of their vapour state

Explanation

**Step-by-Step Solution:**

1. **Understanding Atmolysis**: Atmolysis is a process that involves the separation of gases from a gaseous mixture. This is the fundamental definition we need to understand.

2. **Mechanism of Atmolysis**: The separation occurs through a porous membrane. This membrane allows certain gas molecules to pass through while restricting others.

3. **Rate of Diffusion**: The key factor in the atmolysis process is the rate of diffusion of the gas molecules. Different gases diffuse at different rates depending on their molecular mass and density.

4. **Separation Based on Diffusion Rates**: Gases with a higher rate of diffusion will pass through the membrane more quickly than those with a lower rate of diffusion. Thus, the separation of gases is based on their individual diffusion rates.

5. **Conclusion**: Therefore, atmolysis is specifically the process of separating gases from their gaseous mixture based on their rates of diffusion through a porous membrane.

**Final Answer**: Atmolysis is the process of separation of gases from their gaseous mixture.
