### Reversible and Irreversible

Can someone explain in depth the major differences between reversible and irreversible processes?

### Re: Reversible and Irreversible

A reversible process is one that takes place in equilibrium and is a slow gradual change from one position to the next. Because it is a continuous change, it can be reversed with an opposite reaction. On the contrary, irreversible processes occur when there is a spontaneous action of some sort such as combustion or a spontaneous expansion from instantly equalizing two different pressures. A reversible process is gradual and an irreversible process is instantaneous. This distinction is very important because their properties are notably different, including the difference in amount of work that a reversible system has compared to an irreversible one.
