Answer:

The reaction is reactant-favored

Explanation:

If we take a look at the reaction equation, Zn2+ (aq) + Co (s) Zn (s) + Co2+ (aq) and consider the reduction potential of the species involved

Zn^2+(aq)/Zn(s)= -0.76

Co^2+(aq)/Co(s)= -0.28

It can easily be seen that the reduction potential of zinc is more negative than that of cobalt. Hence the electrochemical reaction is not spontaneous as written but will greatly favour the reverse reaction.
