What is reversible expansion and how does it differ from irreversible expansion?

a reversible expansion is isothermal and therefore expanding at constant temperature and the pressure on the outside of the system is the same as the pressure on the inside. It can be reversed by an infinitesimal change in a variable, whereas an irreversible expansion cannot.

Ok thank you!

It's also good to note that reversible reactions always do more work or have more work done by irreversible reactions, since reversible reactions is the max work done.

reversible expansion will allow you to use the isothermal equation w= nrtln(delta V) while reversible isothermal can only use W=-pdeltaV.
