Can someone please explain why isothermal, reversible processes do more work than their irreversible counterpart?

Isothermal reversible reactions do more work than irreversible reactions, because isothermal reactions have to work against more external pressure than irreversible reactions. Dr. Lavelle gave the example of a boulder at the top of a hill; work has to be done for the boulder to go up the hill, while less has to be done for it to roll down the hill. Hope this helps!

Reversible processes do more work because the work is the integral of many consecutive efforts of changing pressure. Irreversible processes has a constant pressure and only has one whole effort.

Isothermal reversible reactions produce more work because it is done slowly and done with tiny steps and allows the system to come back to equilibrium. Irreversible processes in comparison is one massive push that doesn't achieve the same amount of work because it is less efficient.
