Enthalpy Definition Clarification

Postby makenzie2K » Thu Jan 24, 2019 11:26 am

I noticed that the definition of enthalpy involves the reaction occurring at a constant pressure. I was wondering if other parameters such as volume must also remain constant?

I believe that changing the volume of a container in which the reaction occurs would change the pressure (therefore pressure would not be constant) of the gases in said container according to the equation P=(nRT)/V.

Volume would also need to be constant, as pressure and volume are dependent on each other.
