Calculating enthalpy

Postby Gisela F Ramirez 2H » Sat Feb 23, 2019 9:57 pm

How would I calculate enthalpy in a reaction that has a constant pressure and constant temperature?

At constant temperature, ∆H=0, as there is no change, so I'm not sure why you would be asked to calculate ∆H at constant temperature. Under only constant pressure, ∆H = q (you can solve for ∆H using formulas for/with q).

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
