WebA cyclic process could be reversible or irreversible. Cyclic process are those processes, during which the system undergoes a succession of processes, and eventually ends up at the same state that it started from, thus executing a cycle.

An example of an irreversible process is a spontaneous chemical reaction, or … Web$\begingroup$ Suppose you are operating your process in a cycle where $\Delta U$ and $\Delta S$ are both zero. Both the reversible process and the irreversible process start and end at the same state. The irreversible process uses a great big cycle with large W and large Q, while the reversible process uses a tiny little cycle with small W and small Q.
