Why that the maximum work is done by the reversible expansion?

The reversible expansion does the maximum amount of work because the gas is pushing against the maximum possible external pressure

The irreversible wouldn't be doing the maximum amount of work because the outside pressure was only 1 atm compared to the inside pressure of 2 atm, so this doesn't represent the work against maximum pressure. On the other hand, the reversible pressure is at equilibrium, so it is expanding against the max pressure, therefore, doing more work.
