AB : Isochoric heatingBC : adiabatic expansionCA : isothermal compressionone mole of an ideal gas is taken round the cycle ABCA as in the diagram shown above. What is the efficiency of a heat engine operating on this cycle?a)b)c)d)Correct answer is option 'B'. Can you explain this answer?

Question

Answer

Process CA is isothermal compression and hence heat released in this process is given by

further heat absorbed in isochoric heating process AB is given by Q₂=c_v(T_A-T_B). Where c_v is specific heat capacity at constant volume.
