Find the average kinetic energy per molecule at temperature T for an equimolar mixture of two ideal gases A and B, where A is monoatmic and B is diamtomic.

Explanation

To find the average kinetic energy per molecule at temperature T for an equimolar mixture of two ideal gases A (monoatomic) and B (diatomic), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Degrees of Freedom**:
- For a monoatomic ideal gas (Gas A), the number of degrees of freedom (f) is 3 (translational motion).
- For a diatomic ideal gas (Gas B), the number of degrees of freedom (f) is 5 (3 translational + 2 rotational).
