The standard electrode potential values of elements are as follows:
I) A=0.68 v
II) B=-2.50V
III) C= -0.50 V
The order of their reducing power is :
A
I = II = III

Solution
The correct option is D II > III > I Reducing power is inversely related to SRP ∴ one with maximum SRP will have the least powers ∴order:B>C>A i.e. II>III>I
