The equilibrium constant, K, for the following reaction is 7.00x10-5 at 673 K. NH, I(s) NH3(g) + HI(g)
An equilibrium mixture of the solid and the two gases in a 1.00 L flask at 673 K contains 0.197 mol
NH,1, 8.37x10-3 M NHz and 8.37x10-3 M HI. If the concentration of NH3(g) is suddenly increased to
1.57x10-2 M, what will be the concentrations of the two gases once equilibrium has been reestablished?
[NH3]=?
[HI]=?
