Liquid octane (c8h18) at 25oc, 1 atm and a mass flow rate of 0.57 kg/h enters an internal combustion engine operating at steady state. the fuel burns with air entering the engine in a separate stream at 25oc, 1atm. combustion products exit at 670 k, 1atm with a dry molar analysis of 11.4% co2, 2.9% co, 1.6% o2, and 84.1% n2. the engine develops power at the rate of 3 kw. determine

(a) the balanced reaction equation;
(b) the rate of heat transfer from the engine, in kw.
