Two moles of an ideal gas is expanded isothermally and reversibly from 1 litre t

Question

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

Options:

A . 11.4 kJ

B . −11.4 kJ

C . 0 kJ

D . 4.8 kJ

Answer: Option C
:
C

△ H = n C_{p} △ T s o l u t i o n; s i n c e △ T = 0

so,

△ H = 0
