We will not consider solids in equilibrium expressions. This mean (solids and liquids are not included in the expression for Kc).
Kc = 1.58 x 10-8 = [CO2][NH3]2
1.58 x 10-8 = [CO2][2.5 x 10-3]2
[CO2] = [1.58 x 10-8]/ [2.5 x 10-3]2
[CO2] = 0.002528 M = 2.5 x 10-3 M
[CO2] = 2.5 x 10-3 M

The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA+bB⇌cC+dD the Kc and Kp expressions are given by Kc=[C]c[D]d[A]a[B]b Kp=(PC)c(PD)d(PA)a(PB)b The subscript c or p indicates whether K is expressed in terms of concentrations or pressures. Equilibrium-constant expressions do not include a term for any pure solids or liquids that may be involved since their composition...

Deriving concentrations from data The equilibrium constant, K, of a reaction at a particular temperature is detemined by the concentrations or pressures of the reactants and products at equilibrium. In Part A, you were given the equilibrium pressures, which could be plugged directly into the formula for K. In Part B however, you will be given initial concentrations and only one equilibrium concentration. You must use this data to find all three equilibrium concentrations before you can apply the formula...
