# Irreversible reaction in a battery

Hello,

Inside an ideal battery, the chemical reaction is reversible (at equilibrium), thus the oxydation-reduction reaction Zn + Cu2+ = Zn2+ + Cu is happening in both ways at the same rate right?

Now, for a real battery, there's resistivity inside it due to many factors, thus the chemical reaction is irreversible. My question is, during the irreversible reaction, is the reaction happening in both ways but at different rate due to resistivity inside the battery or it is just like the combustion reaction happening in one way?

Thanks

Please elaborate. "Reversible" and "at equilibrium" are two different things, I don't see why you are mixing them.

Sorry but chemistry is not my domain. I thought that a chemical reaction at equilibrium thus it is a reversible reaction.
