The standard emf of a galvanic cell inv...

The standard emf of a galvanic cell involving 2 motes of electrons in its redox reaction is 0.59 V the equilibriun constant for the redox reaction of the cell is

A

`10^(20)`

B

`10^(5)`

C

10

D

`10^(10)`

Text Solution

Verified by Experts

The correct Answer is:
A
`nFe^(@)=2.303 RT log k_(p)`
`=(2xx96500x0.59)/(2.303xx8.314 xx 298)=19.9 = 20.0`
`k_(p)= "antilog" 20.0=1 xx10^(20)`
