Compare the rates of diffusion of ` '^(235)UF_(6)` and ` '^(238)UF_(6)`

Explanation

To compare the rates of diffusion of `^(235)UF_(6)` and `^(238)UF_(6)`, we can use Graham's law of effusion. This law states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.

### Step-by-Step Solution:

1. **Identify the Molar Masses**:
- For `^(238)UF_(6)`:
- Molar mass = 238 (for U) + 6 × 19 (for F) = 238 + 114 = 352 g/mol.
- For `^(235)UF_(6)`:
