Can someone please clarify the definitions of and differences between reversible and isothermal expansion? Thanks!

A reversible isothermal reaction is one in which the volume changes slowly at a constant temperature. There is no heat transfer, so q=0, so deltaU=w.

I believe that a reversible expansion is when the change in pressure is infinitesimal so that the Pinternal~Pexternal and the V change is also infinitesimal. A isothermal expansion is an expansion with constant temperature.

Just to be clear, Dr. Lavelle said this wouldn't be on this week's test right?
