What is the difference between Cyclic Process and Reversible Process?
The key concept in a reversible process is that the system is in equilibrium with it's surroundings at every instant. A cyclic process is different: in a cyclic process, the initial and final state are the same.
The graph that you have drawn consists of a reversible isothermal expansion(AB) and a reversible isothermal contraction(BA). Overall, the process A-&gt;B-&gt;A is a cyclic process made up of two reversible processes.
