Q5 / 150 · MHT CET 2007 · Chemistry

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

  • A
    $H+E=p V$
  • B
    $E=H+p \Delta V$
  • Correct answer
    C
    $q_{p}=q_{v}+\Delta n R T$
  • D
    None of the above

Solution

The heat of reaction for an ideal gas, at constant pressure and constant volume are related as $$ \begin{array}{ll} \therefore & \Delta H=\Delta E+\Delta n R T \\ \because & q_{p}=q_{V}+\Delta n R T \end{array} $$

Hence, the correct answer is option: 'C'.
