Work Done for Irreversible Isothermal Expansion of an ideal gas -

W= -P_{ext}\left ( V_{f} -V_{i}\right )

- wherein

P_{ext} may be equal to P_{f} or may not be equal to P_{f}, but work done is always calculated by P_{ext}

As we have learned in isothermal expansion

PV_{m}=K

P=\frac{K}{V_{m}}

The correct graphs are
