Here are the E° values for all the steps of the reduction from vanadium(V) to vanadium(II):
. . . and here is the zinc value again:
Remember that for the vanadium reactions to move to the right (which is what we want), their E° values must be more positive than whatever you are reacting them with. In other words, for the reactions to work, zinc must always have the more negative value - and that's the case. Zinc can reduce the vanadium through each of these steps to give the vanadium(II) ion.
