The heat of combusion of benzene in a bomb calorimeter (i.e constant volume) was found to be `3263.9kJ mo1^(-1)` at `25^(@)C` Calculate the heat of combustion of benzene at constan pressure .

Explanation

To calculate the heat of combustion of benzene at constant pressure from the heat of combustion at constant volume, we can follow these steps:

### Step 1: Understand the Given Data
The heat of combustion of benzene at constant volume is given as:
\[ \Delta U = -3263.9 \, \text{kJ/mol} \]
at a temperature of \(25^\circ C\) (which is \(298 \, \text{K}\)).
