Why are Reversible processes do more work than irreversible processes?

irreversible processes are done under constant pressure while reversible are not, and since w is a product of pressure and volume, work is higher when pressure is not constant because the gas will have to do more work

Wrev is an ideal situation with constant Temperature; Wirr is the more realistic and non-constant Temperature scenario and thus it does less work.

Irreversible processes are done under pressure that remains constant whereas reversible processes aren't. Gases have to do more work when pressure is not constant, which is why reversible processes do more work.

Reversible processes can be thought of as the maximum work possible done by the gas, as external pressure constantly changes in order to match the internal pressure. Irreversible processes simply have constant external pressure, so the work done would not be as high.
