Liquid methanol (CH3OH) can be used as an alternative fuel in pickup and SUV engines. An industrial method for preparing it uses the catalytic hydrogenation of carbon monoxide: catalyst CO(g) + 2H2(g) > CH3OH(l) How much heat (in kJ) is released when 15.0 L of CO at 85°C and 112 kPa reacts with 11.8 L of H2 at 75°C and 744 torr?
