In the first case, a Carnot engine operates between reservoirs at temperatures of 300 K and 100 K. In the second case, two Carnot engines are connected in series between the same initial and final reservoirs (300 K and 100 K), where the intermediate temperature is chosen such that the efficiency is maximized or equalized. The overall efficiency of this series combination in the second case will be:
