    Stuck on the question below, if anyone could explain the answer to me..

    Refer to the standard electrode potentials for the four chemical equations below to decide which describes a reaction which is energetically feasible.

    Are you provided with a "Data Booklet" during your exam? The Standard Electrode Potential values in it would help you to solve this question.

    Yes I am. However when using the booklet it seems that there is no answer to this question if you attempt it you will see why.

    Remember that the reduction potentials in the table are half-equations.

    The ones in the question in the OP are full-equations.

    So for each reaction, you need to separate the full-equation into half-equation, and then work out the feasibility of the overall reaction.
