Find the actual efficiency and the theoretical efficiency. Find the heat exhausted to the cold reservoir. Find the entropy change of the hot reservoir and the cold reservoir, and the net change of entropy of the entire engine. (For this finding the change in entropy, Qh is negative as energy is leaving the reservoir, Qc is positive)
