By applying Hess's law and using the enthalpy of formation values for the products and reactants, we can determine the overall enthalpy change for the reaction. The goal is to find the enthalpy change, which is given as -3267.0 kJ/mol, indicating that the combustion of benzene is an exothermic process."}
