So this is our anode and this is our cathode. So what happens is two electrons leave this atom forming our aqueous iron atom and these two electrons travel via the conductor to this guy reacting with this positively charged atom forming our solid cadmium. So let's go to step two. Now, in step two and three, what we want to do or do is find a cell voltage of our electrochemical cell and then use the cell voltage to find our equilibrium constant KC. So let's go to step two. Now, this is our formula that we want to use to find the cell voltage where this is the cell voltage of the reduction reaction and the cell voltage of the oxidation reaction.
