isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$

Work in Reversible Process vs Work in Irreversible Process

The textbook states that "Provided the initial and final states are the same, a change carried out reversibly always does more work than a change carried out irreversibly"?

Why is the amount of work a system can do greater in reversible processes as opposed to in irreversible processes?

Re: Work in Reversible Process vs Work in Irreversible Proce

In a reversible process, you don't lose energy as heat, while in an irreversible process, some energy is lost as heat.

Are open, closed, or isolated systems reversible?

Re: Work in Reversible Process vs Work in Irreversible Proce

If you graph the two, it is pretty easy to see that a reversible process does more work. The area under the curve is greater.
