The equilibrium constant for the reaction of bromine and chlorine to form bromine chloride under certain conditions is 4.7x10-2.
Cl2(g) + Br2(g) --> 2BrCl(g) K= 4.7 x 10-2

What is the equilibrium constant for the following reaction under the same conditions?
1/2 Cl2(g) + 1/2 Br2(g) --> BrCl(g) K=?

Thanks.

  • Chemistry -

    k= [BrCl]^2 / [Cl2][Br2]

    in the second reaction,
    k'= [BrCl2]/[ Cl2]^.5 [Br2]^.5= sqrt k

    check my reasoning.
