Questiоn 11, pаrt e.Questiоn 11: Hess lаw аnd temperature-dependent reactiоn enthalpyEthanol combustion can be written as C2H5OH(l) + 3 O2(g) -> 2 CO2(g) + 3 H2O(l). Use standard formation enthalpies at 298 K: C2H5OH(l) = -277.0 kJ mol^-1, CO2(g) = -393.5 kJ mol^-1, H2O(l) = -285.8 kJ mol^-1, and O2(g) = 0. Use constant molar heat capacities: C2H5OH(l) = 112.4 J mol^-1 K^-1, O2(g) = 29.4 J mol^-1 K^-1, CO2(g) = 37.1 J mol^-1 K^-1, and H2O(l) = 75.3 J mol^-1 K^-1.Part e. Calculate the heat-capacity correction from 298 K to 350 K.
