Two moles of an ideal gas is expanded is...

Two moles of an ideal gas is expanded isothermally and reversibly from `1` liter to `10` liter at `300 K`. The enthalpy change (in `kJ`) for the process

A

11.4 kJ

B

`-11.4 kJ`

C

0 kJ

D

4.8 kJ

Text Solution

Verified by Experts

The correct Answer is:
C

`Delta H =""_(n)C_(P) Delta T," since "Delta T=0" hence, "Delta H=0`
