Now let's look at which one is more likely to occur. Now, for reduction, it's the opposite. The more positive it is, the more likely it is to occur. So whatever is higher up on the reduction half reaction table, that guy will be more likely to undergo reduction. So since this is more positive, that means this will be our reduction reaction. So now we must add up all these reactions except this one, because this one won't occur, this one will occur, this one will occur, and this one won't occur.
