Question

Consider this equilibrium reaction at 400 K.

Br2(g)+Cl2(g)↽−−⇀2BrCl(g)𝐾c=7.0

If the composition of the reaction mixture at 400 K is [BrCl]=0.00608 M, [Br2]=0.00181 M, and [Cl2]=0.000332 M, what is the reaction quotient, 𝑄 ?

Answer 1

Br₂(g) + Cl₂(g) <==> 2BrCl(g) Kc = 7.0

0.00181...0.000332......0.00608

Q = [BrCl]² / [Br₂][Cl₂] = (0.00608)² / (0.00181)(0.000332)

Q = 61.5

If the question also asks about shifting toward equilibrium, the reaction will shift to the left because Q > Kc
