Expansion Work

Postby Aman Sankineni 2L » Tue Feb 11, 2020 8:57 pm

How do we tell if a reaction does expansion work or not?

If the volume increases then there is expansion work.

Expansion work only corresponds to a change in volume. If there is no change in volume, there is no expansion work (or any work done at all if you are talking about an irreversible reaction).

There is also no expansion work if there's a vacuum

If the products side has moles of gas than the reactants side, then the reaction has done expansion work.

Expansion does work if there is an external pressure and the volume increases.
