4. Consider the complete, constant pressure combustion of toluene (CHs) with air as given below: CH8 + 20 (O2 + 3.76 N2) = ? The reactants are initially at 298 K. (1) Assuming complete combustion, balance the reaction equation. (2) Assuming constant specific heats, as given below, find the adiabatic flame temperature.
