A diatomic ideal gas acts as a heat engine following a process described by the diagram below: Step 1. Isothermal expansion at ThotThot from volume VaVa to a final volume VbVb. The final volume is a factor kk times larger than the initial volume (ie. VbVb=kVakVa).
Step 2. Isobaric contraction from volume VbVb back to original volume VaVa, and cooling from ThotThot to TcTc
Step 3. Isochoric heating returning the system to its original state.

If there are n=82.4mols of the gas, the expansion factor kk=3.2, and initial temperature ThotThot=217.8K, what is the efficiency ee of this cyclic heat engine?
