JEE Main PAPER - 1

The combustion of benzene (l) gives $CO_2(g)$   and $H_2O(l)$  . Given that heat of combustion of benzene at constant volume is $-3263.9 \text{ kJ mol}^{-1}$   at $25^\circ\text{C}$  ; heat of combustion (in $\text{kJ mol}^{-1}$  ) of benzene at constant pressure will be: $(R = 8.314 \text{ J K}^{-1} \text{ mol}^{-1})$
