$CH _{3} OH (1)+\frac{3}{2} O _{2}( g ) \rightarrow CO _{2}( g )+2 H _{2} O (1)$
the amount of heat produced as measured by bomb calorimeter is $726 \,kJ\, mol ^{-1}$ at $27^{\circ} C$. The enthalpy of combustion for the reaction is $- x \,kJ\,mol ^{-1}$, where $x$ is $.....$ (Nearest integer)
$\left(\right.$ Given $: R =8.3\, J\,K ^{-1} \,mol ^{-1}$ )
Reason : In presence of $H_2SO_4$, $HNO_3$ acts as a base and produces $NO_2^+$ ions.
(Nearest integer)
[Given : The heat capacity of the calorimeter system is $20\, kJ\, K ^{-1}, R =8.3\, JK ^{-1}\, mol ^{-1}$.
Assume ideal gas behaviour.
Atomic mass of $C$ and $H$ are $12$ and $1\, g\, mol ^{-1}$ respectively]
