Question

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. `-11.4kJ`
C. `0 kJ`
D. `4.8 kJ`

Answer 1

Correct Answer - C
For an isothernal and reversible process, `DeltaT=0`
`:. DeltaH=DeltaU=0`
