Acell is constructed of the following two half cells.
ag+ + e⇌ ag + 0.80 v al3+ 3e ⇌ al - 1.67v
what is e+ of the cell?
a: 2.47 v
b: 0.087 v
c: -0.87 v
d: 5.81 v
explain

I believe the correct answer from the choices listed above is option A. The E+ of the cell would be 2.47 V. E of the cell is given by the formula E(cathode) - E(anode) . So in this case the first half cell reaction is the reaction that takes place in the cathode and the second one takes place in the anode.
