So we begin with a certain electrochemical cell that's composed of cadmium and zinc. Now, we are given the cell voltage or the electromotive force around cells, and it's given to be zero point 36 volts. Under standard conditions, that means 1 bar pressure and one molar concentration. Now, this guy is also at 25 degrees Celsius. So we are also given the cell voltage for one of the two half reactions, one of the two half cells. And the zinc half reaction is given negative zero point 76 volts.
