Reversible Process Vs Irreversible Process

Reversible Process	Irreversible Process
The process in which the direction may be reversed at any stage by merely a small change in a variable like temperature, pressure, etc.	A process in which the direction cannot be reversed at any stage by change in a variable like temperature, pressure, etc.
In a reversible process, the driving force is only infinitesimally greater than the opposing force at all stages.	The driving force is different than the opposing force.
It is carried out infinitesimally slowly.	It is carried out rapidly.
At any stage during the process, equilibrium is not disturbed.	Equilibrium may exist only after the completion of the process.
It is only imaginary and cannot be achieved in actual process.	All natural processes are irreversible.
Work obtained in this process is maximum.	Work obtained in this process is not the maximum.
