The standard reduction potential values of three metallic cation, X, Y, Z are 0.53,-3.04 and -1.18 Vrespectively. The order of reducing power of the corresponding metal is (a) Y> Z>X (b) X>Y>z (c) Z>Y>X (d) Z>X>Y
The metal with least standard reduction electrode potential has the highest reducing power and vice-versa. Therefore, the order of the reducing power of these metals is Y>Z>X
