What is the value of the equilibrium constant at 25 oC for t

What is the value of the equilibrium constant at 25 ^oC for the reaction between the pair:

Br2(l) and Cl^-(aq)

Use the reduction potential values for Br2(l) of +1.07 V and for Cl2(g) of +1.36 V

Solution

Br2 + 2Cl- --->2Br- +Cl2

so,

Eo=-1.36+1.07

=-0.29 V

so,

Eo=(0.059/2) *log(k)

or -0.29=(0.059/2) * log(k)

or k=1.477*10^-10
