Suppose this hypothetical situation, A(3+) => (-1.00 V) A(2+) => (-0.1 V) A(+)
From A(3+) => A(+), consequently, it is -0.55V.
If the anode reaction is +0.70 V, can it push A(3+) to A(+)?
On one side, you can say that the (A(3+) to A(+)) reaction is -0.55 V, and thus, the overall reaction is +0.15 V.
However, if you look at A(3+) to A(2+), which is the first step, the reaction is nonspontaneous because -1.00+0.70=-0.30 V.
So, the question is can A(3+) go to A(+)?
Thanks a lot
