Do I Need a Battery for a Positive Redox Reaction?

AI Thread Summary
In reactions with a positive electric potential, such as one with E=1.34V, it is not necessary to connect electrode terminals to an external battery to provide that voltage. If the reaction can occur spontaneously, the electrodes will inherently possess the required potential. This indicates that spontaneous reactions can generate the necessary voltage without external assistance, emphasizing the self-sustaining nature of certain electrochemical processes.

For a reaction where the electric potential is positive, does there need to be something to provide voltage for the reaction to occur? Let's say E= 1.34V for the reaction. Do I need to connect the electrode terminals to a battery to provide 1.34V?

Nope. As long as the reaction can occur spontaneously, the electrode terminals will have a potential.
