Reactions at constant pressure

Postby Clara Cho 2K » Sun Feb 09, 2020 10:47 am

Why is is PdV insignificant when a reaction is at constant pressure and involves solids and liquids?

I think it's because it is very difficult to change the volume of solids and liquids by a significant amount.

For solids and liquids, the volume is difficult to change when the pressure is constant, also the number would be so small that it is negligible.
