Isothermal Irreversible

Postby Renee Grange 1I » Sun Feb 09, 2020 10:14 pm

Is it possible for isothermal reactions to be irreversible, if so, how?

I suppose if the pressure inside the vessel is different from the external pressure, then there will still exist a definite direction of spontaneous change, which would make the reaction irreversible.

That said, the reaction will somehow have to be kept at constant temperature in order to fulfill your original condition, since it would otherwise cool as the gas expands.

Please correct me if I'm wrong!

I agree! I believe isothermal expansions are irreversible because they progress towards a uniform state, which is an irreversible change.

Yes, it is possible for isothermal reactions to be irreversible.
