MCQ
Two mole of an ideal gas is expanded isothermally and reversibly from $1$ litre ot $10$ litre at $300\,K$. The enthalpy change (in $kJ$) for the process is .....$kJ$
  • A
    $11.4 $
  • B
    $-11.4$
  • ✓
    $0$
  • D
    $4.8$
✓

Answer

Correct option: C.
$0$
(c)$\Delta H = nCp\,\Delta T$
The process is isothermal therefore
$\Delta G = 0$; $\therefore \,\,\Delta H = 0$
