Reducing power of metal propto (1/SRP) K > Al > Cr > Ag.

Q. The standard electrode potential ( $E^{\circ}$ ) values of $A l^{3 +} / A l$ , $A g^{+} / A g$ , $K^{+} / K$ and $C r^{3 +} / C r$ are $- 1.66 V$ , $0.80 V$ , $- 2.93 V$ and $- 0.74 V$ , respectively. The correct decreasing order of reducing power of the metal is :

Ag > Cr > Al > K

K > Al > Cr > Ag

K > Al > Ag > Cr

Al > K > Ag > Cr

Reducing power of metal $\propto \frac{1}{SRP}$
$K > A l > C r > A g$ .
