Question

Bromine monochloride, BrCl decomposes into bromine and chlorine and reaches the equilibrium:

for which K_c= 32 at 500 K. If initially pure BrCl is present at a concentration of 3.3 × 10^–3 molL^–1, what is its molar concentration in the mixture at equilibrium?

Answer 1

Let the amount of bromine and chlorine formed at equilibrium be x. The given reaction is:

Now, we can write,

Therefore, at equilibrium,
