The relation between work done in reversible and irreversible process is

Options

  1. AW_ irr >W_ rev
  2. BW_ irr < W_ rev
  3. CW_ irr =W_ rev
  4. DW_ irr W_ rev

Correct answer

B. W_ irr < W_ rev

Step-by-step solution

For a given change in state of a system, the work done in a reversible process is the maximum work that can be obtained from the system during expansion, or the minimum work that must be done on the system during compression. In an irreversible process, the system undergoes a spontaneous change where the external pressure is not balanced by the internal pressure at every instant, leading to a loss of energy as heat due to friction or turbulence. For expansion, the work done by the system in a reversible process is
