Consider the Figure shown in which X represent Zn(s), T represents Co(s), and S is a solution that is 1.0 M in Co2+.

At which electrode does reduction occur? The reduction potentials of Co2+ and Zn2+ are -0.27 V and -0.76 V, respectively.

Would it be T, since Co(s) reduces to Co2+?

Would it be T, since Co(s) reduces to Co2+?

What you have written isn't a reduction, its the other way round.
In general you can tell which species is going to be reduced just by looking at which has the more positive reduction potential.
