$CH _{3} OH (1)+\frac{3}{2} O _{2}( g ) \rightarrow CO _{2}( g )+2 H _{2} O (1)$
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 $: R =8.3\, J\,K ^{-1} \,mol ^{-1}$ )
Assertion $A :$- Carbon forms two important oxides $- CO$ and $CO _2 . CO$ is neutral whereas $CO _2$ is acidic in nature.
Reason $R :$- $CO _2$ can combine with water in a limited way to form carbonic acid, while $CO$ is sparingly soluble in water.
In the light of the above statements, choose the most appropriate answer from the options given below :-
