Answer 2

Answer:

The initial concentration of BrCl,Br

2 and Cl2 are 3.30×10^−3M, 0M and 0M respectively.

Let x M be the amount of BrCl dissociated.

The equilibrium concentrations are (3.30×10^−3 ×10^−3 −x),x/2,x/2 respectively.

The equilibrium constant expression is

Kc = [Br2][Cl2]/[BrCl]2

= x/2 • x/2 / (3.30×10^−3 −x)² = 32

Hence, the equilibrium concentration of BrCl is 3.30×10^−3 −3.00×10^−3

=0.30×10^−3

=3.0×10^−4M
