$C{H_{4(g)}} + 2{O_{2(g)}} \to C{O_{2(g)}} + 2{H_2}{O_{(g)}}$
Number of intramolecular aldol condensation product is
Step $I\,\,:$ ${H_2}O(g)\, \to \,H(g)\, + \,OH(g)\,;$ $\Delta H = 498\,kJ\,mol^{-1}$
Step $II\,\,:$ $OH(g)\, \to \,H(g)\, + \,O(g)\,;$ $\Delta H = 428\,kJ\,mol^{-1}$
The bond enthalpy of the $O-H$ bond is....$kJ\,mol^{-1}$
$2 SO _2( g )+ O _2( g ) \rightleftharpoons 2 SO _3( g ), \Delta H =-190\,kJ$
