10.4 kg of a gas expands isothermally and reversibly. The work done is maximum if the gas is

A

`NO_(2)`

B

`Cl_(2)`

C

`CH_(4)`

D

`O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
The work done is directly proportional to the number of moles and inversly proportional to the molecular mass. Molecular mass of `CH_(4)` is minimum among all.
