$\mathop C\limits^\Theta {H_3},\mathop N\limits^\Theta {H_2},\,\mathop O\limits^\Theta H,\,\mathop C\limits^\Theta l$
$PC{l_5}\, \rightleftharpoons \,PC{l_3}\, + \,C{l_2}\,;\,{K_C} = \,0.0414\,mol\,{L^{ - 1}}$
$C + {O_2} \to C{O_2};\,\Delta H = - 394\,kJ\,mo{l^{ - 1}}$
$2CO + {O_2} \to 2C{O_2};\,\Delta H = - 569\,kJ\,mo{l^{ - 1}}$ The heat of formation of $1\,mol$ of carbon monoxide is thus .....$kJ\,mo{l^{ - 1}}$
