(Answered) Assume that the change in concentration of cocl2 is small

Academics

Assume that the change in concentration of COCl2 is small enough to be neglected in the following problem.

(a) Calculate the equilibrium concentration of all species in an equilibrium mixture that results from the decomposition of COCl2 with an initial concentration of 0.3166 M. COCl2(g) ? CO(g) + Cl2(g) Kc = 2.2 × 10-10

(b) Show that the change is small enough to be neglected
