When examining the Pex vs V graph for reversible and irreversible, the area under the reversible curve is greater because Pex can change as well, so it is maximized. Any little change is responded to, whereas in irreversible reactions, super small changes don't really have an effect.

Reversible expansion does the most amount of work because the gas is pushing against the maximum possible external pressure and less of the energy is lost to heat.
