What is the difference between Reversible and Irreversible process?

Ans: The difference between Reversible and Irreversible process is given bilow.

Reversible Process	Irreversible Process
1. It takes place in infinite number of infinitesimally small steps and it would take finite time to occur.	1. It takes place infinite time.
2. It is imaginary as it assumes the presence of frictionless and weight less piston.	2. It is real and can be performed actually.
3. It is in equilibrium state at all stage of the operation.	It is in equilibrium state only at the initial and final stage of the operation.
4. All changes are reversed when the process is carried out in reversible direction.	4. After this type of process has occurred all changes do not return to the initial stage by themselves.
5. It is extremely slow.	5. It proceeds at measureable speed.
6. Work done by a reversible process is greater than the corresponding irreversible process.	6. Work done by a irreversible process is smaller than the corresponding reversible process.
