Can you have one half-reaction take place, without the other half-reaction taking place immediately?
The other half-reaction takes place when
the cell potential is raised.
I half witness this in some electrochemical cells.
Sincere Thanks.

    It wont occur very long, as charge builds up, and will stop the reaction.
