An ideal gas is allowed to expand against a constant pressure of 2 bar from 10L to 50 L in one step. Calculate the amount of work done by the gas. If the same expansion were carried out reversibly, will the work done be higher or lower than the earlier case ?
(Give that, 1 L bar = 100 J)

Explanation

To solve the question, we will follow these steps:

### Step 1: Identify the given values
- External pressure (P_external) = 2 bar
- Initial volume (V_initial) = 10 L
- Final volume (V_final) = 50 L
- Conversion factor: 1 L bar = 100 J
