Answer:
-1.84 V
Explanation:
Eocell = Ecathode - Eanode
From the equation (the one that they give us), we can see that Cl2 is being reduced (it is gaining electrons).
Reduction always happens at the cathode, so we now know that the standard reduction potential of Cl2 is the Ecathode value
So, we can set up the equation like this:
3.2 V = 1.36 V - x
Solving for x gives us:
x = -1.84 V
Hope this helps!
