Calculate total and individual w, q, ?U, ?H, and ?S of an Otto engine operating on stoichiometric ethanol - oxygen gas mixture, with cylinder volume of 3 l and compression ratio of 21:1. Enthalpy of combustion of ethanol(g) is -1371 kJ/mol. Temperature and pressure of intake mixture is 25 oC and 1 bar, respectively. Assume ideal behavior of diatomic gas and ignore the changes in the number of moles of gas during combustion.
