Question

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
• B. I > III > II
• C. III > II > I
• D. II > III > I

Answer 1

The correct option is D II > III > I

Reducing power is inversely related to SRP
$\therefore$ one with maximum SRP will have the least powers
$\therefore order:B>C>A$
i.e. $II>III>I$
