Question

Difference between reversible and irreversible work done

Answer 1

In a reversible process, at each point along the process path, the system is only slightly removed from being in thermodynamic equilibrium with its surroundings. For a reversible process, the system is ALWAYS in equilibrium with its surroundings. For an irreversible process, there will ALWAYS be an entropy change.

Answer 2

In a reversible process, at each point along the process path, the system isonly slightly removed from being in thermodynamic equilibrium with its surroundings. For a reversible process, the system is ALWAYS in equilibrium with its surroundings. 

The work done in an reversible process is given by:
W=RΔT1−γW=RΔT1−γ

The work done in an irreversible process is given by:
W=PextΔV
