Consider this equilibrium reaction at 400 K. $$Br_2(g) + Cl_2(g) \rightleftharpoons 2BrCl(g)$$ $$K_c = 7.0$$ If the composition of the reaction mixture at 400 K is $$[BrCl] = 0.004150 M$$, $$[Br_2] = 0.003660 M$$, and $$[Cl_2] = 0.0006720 M$$, what is the reaction quotient, Q? Q = 792.522 Incorrect Answer How is the reaction quotient related to the equilibrium constant, $$K_c$$, for this reaction? Q < Kc Q = Kc Q > Kc Incorrect Answer >>
