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. setting microphone volume

"In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible. In thermodynamics, a change in the thermodynamic state of a system and all o… " - Irreversible cycle
