What are the factors affecting the rate of diffusion?

Explanation

### Step-by-Step Solution

1. **Understanding Diffusion**:
- Diffusion is the process by which substances move from an area of high concentration to an area of low concentration. This movement continues until equilibrium is reached.

2. **Factors Affecting the Rate of Diffusion**:
- **Pressure**:
- The rate of diffusion is influenced by pressure. Gases diffuse from areas of high pressure to areas of low pressure. The greater the difference in pressure, the faster the rate of diffusion.
