Isotherm T=423 K 2. The above figure shows the PV diagram for a reversible heat engine that uses 2mol. of Hydrogen gas as the operating substance. The cycle starts from point a at 1X105 Pa pressure and 20°C. a) Is the path of the cycle carried out clockwise or counter clockwise? *. b) Calculate AEint, Q and W for each segment. c) What is the efficiency of this heat engine?. d) Compare its efficiency with that of a Carnot engine operating between the same temperatures. (1 atmospheric pressure=101325Pa)
