(Answered) The equilibrium constant k for the following reaction

Academics

The equilibrium constant, K, for the following reaction is 5.10×10^-6 at 548 K.

NH₄Cl(s) <-----> NH₃(g) + HCl(g)

An equilibrium mixture of the solid and the two gases in a 1.00 L flask at 548 K contains 0.252 mol NH₄Cl, 2.26×10^-3M NH₃ and 2.26×10^-3 M HCl. If the concentration of NH₃(g) is suddenly increased to 3.91×10^-3 M, what will be the concentrations of the two gases once equilibrium has been reestablished?

[NH₃] = ? M

[HCl] = ? M
