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

Options

A. `10^(20)`
B. `10^(5)`
C. 10
D. `10^(10)`

Answer

A

Explanation

For equilibrium `E^(@) = (0.059)/(n) log k eq Rightarrow 0.59= (0.059)/(2) log Keq`
or `log Keq = 20 Rightarrow Keq = 10^(20)`
