The molar heat capacity for a gas at constant `T` and `P` is

Options

A. `(3)/(2)R`
B. `(5)/(2)R`
C. Dependent on the atomicity of the gas
D. Infinity

Explanation

To solve the question regarding the molar heat capacity for a gas at constant temperature and pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Molar Heat Capacity**:
Molar heat capacity (C) is defined as the amount of heat required to change the temperature of one mole of a substance by one degree Celsius (or one Kelvin). It can be expressed mathematically as:
\[
C = \frac{dH}{dT}
