Answer 2

what is the entire equation because you should be able to set it up as kc=(concentrations of products)/(concentrations of reactants). Also the balanced chemical equation will tell you to what power the concentration is raised to.

Answer 3

2BrCl ==> Br2 + Cl2

K = 0.142 = (Br2)(Cl2)/(BrCl)^2
Substitute and solve for the only unknown you have; i.e., (BrCl)
