Expert Answer:

Dear student,
The process in which the system and surroundings can be restored to the initial state from the final state without producing any changes in the thermodynamics properties of the universe is called as the reversible process.let us suppose that the system has undergone change from state A to state B. If the system can be restored from state B to state A, and there is no change in the universe, then the process is said to be reversible process. The reversible process can be reversed completely and there is no trace left to show that the system had undergone thermodynamic change.

Examples of reversible reactions: dissolution of a salt into water, reaction of O2 and H2 to form water, phase changes like freezing or boiling of water

Hope this helps.
