Enthalpies of Formation (Section)
Ethanol (C2H5OH) is currently blended with gasoline as an automobile fuel. (a) Write a balanced equation for the combustion of liquid ethanol in air.
(b) Calculate the standard enthalpy change for the reaction, assuming H2O(g) as a product. (c) Calculate the heat produced per liter of ethanol by combustion of ethanol under constant pressure. Ethanol has a density of 0.789 g/mL. (d) Calculate the mass of CO2 produced per kJ of heat emitted.
