For an ideal gas,the heat of reaction at constant pressure and heat of reaction at constant volume are related by the equation:

  • A
    $\Delta H = \Delta U + P \Delta V$
  • B
    $U = H + P \Delta V$
  • C
    $\Delta U = \Delta H + \frac{\Delta n}{RT}$
  • D
    $\Delta H = \Delta U + \Delta nRT$
