The standard enthalpies of formation of \( \mathrm{CO}, \mathrm{NO}_{2} \)
P and \( \mathrm{CO}_{2} \) are \( -110.5 \mathrm{~kJ} \mathrm{~mol}^{-1},-33.2 \mathrm{~kJ} \mathrm{~mol}^{-1} \) and

W \( -393.5 \mathrm{~kJ} \mathrm{~mol}^{-1} \) respectively. The standard enthalpy of the reaction is: \( 4 \mathrm{CO}(\mathrm{g})+2 \mathrm{NO}_{2}(\mathrm{~g}) \rightarrow 4 \mathrm{CO}_{2}(\mathrm{~g})+\mathrm{N}_{2}(\mathrm{~g}) \) is
(1) \( -1065.6 \mathrm{~kJ} \)
(2) \( -200 \mathrm{~kJ} \)
(3) \( -700 \mathrm{~kJ} \)
(4) \( 850 \mathrm{~kJ} \)
