delta H for Isothermal Reversible Expansion

Postby Lily Guo 1D » Wed Feb 14, 2018 12:15 am

Is it possible to find delta H for an isothermal reversible expansion?

Yes. You must use H = U + PV and differentiate. However, for ideal gases, enthalpy is strictly a function of temperature and thus it is zero for isothermal processes.
