When 0.532g of benzene `(C_(6)H_(6))`, boiling point 353 K, is burnt with excess of oxygen in a constant volume system 22.3 kJ of heat is given out. Calculate `DeltaH` for the combustion process `(R=8.31 JK^(-1) mol^(-1))`.

Explanation

To calculate the enthalpy change (ΔH) for the combustion of benzene, we will follow these steps:

### Step 1: Write the balanced combustion reaction for benzene
The balanced chemical equation for the combustion of benzene (C₆H₆) in excess oxygen (O₂) is:

\[ 2 C_6H_6 + 15 O_2 \rightarrow 12 CO_2 + 6 H_2O \]
