Two moles of an ideal gas expanded isothermally and reversibly from `1L` to `10L` at `300K`. What is the enthalpy change?

Options

A. `4.98 kJ`
B. `11.47 kJ`
C. `-11.47 kJ`
D. `0 kJ`

Explanation

To find the enthalpy change (ΔH) for the isothermal expansion of an ideal gas, we can follow these steps:

### Step 1: Understand the conditions of the process
The problem states that we have an ideal gas expanding isothermally and reversibly from 1 L to 10 L at a temperature of 300 K.

### Step 2: Recall the definition of enthalpy change
The enthalpy change (ΔH) for a process is given by the equation:
\[ \Delta H = nC_p\Delta T \]
