### Reversibly & Isothermally

What does it mean when a system is expanding reversibly and isothermally?

I think it refers to the work, and which equation you would use in your calculations. You would use W=-nRTln(V2/V1).
It also means that deltaU is 0

What is the difference between reversible and irreversible reactions (conceptually, not mathematically)?

### Re: Reversibly & Isothermally

In reversible reactions, reactants react with other reactants to form products, and the products react with other products to form more reactants. Essentially, it is a reaction cycle.

In an irreversible reaction, reactants react with other reactants to form products, and the products do not form reactants.

hope this helped
