Question

The standard electrode potential (Eo) for OCl−/Cl− and Cl−/12Cl2 respectively are 0.94 V and – 1.36 V, then the Eo value for OCl−/12Cl2 will be

Answer 1

Answer:

The standard electrode potential for OCl-/Cl- and Cl-/1/2Cl2 respectively are 0.94V and -1.36V.

Answer 2

Answer:

0.52 V

Explanation:

Ecell OCl-/Cl- = 0.94 V
Ecell Cl-/ 1/2Cl2 = -1.36 V

OCl- ------> Cl-            .........(1)    n = 3  G1
   Cl- -------> 1/2 Cl2    .........(2)   n = 1   G2

adding (1) and(2) ,
OCl- -------> 1/2 Cl2     .........(3)   n = 1   G3

G3 = G1 + G2

-1 x F x E3 = -3 x F x E1 + ( -1 x F x E2)

E3 = 0.52 V
