The equilibrium constant Kc for the reaction involving ammonia (NH3) and ammonium (NH4) can be determined using the concentrations of the reactants and products at equilibrium.
The balanced equation for the reaction is:
NH3 ⇌ NH4+
The initial concentration of NH3 is 7 mol / 14 L = 0.5 M. At equilibrium, the concentration of NH4+ is 0.2 M.
The equilibrium constant Kc is given by:
Kc = [NH4+] / [NH3]
Substitute the given values into the equation:
Kc = 0.2 / 0.5 = 0.4
Therefore, the equilibrium constant Kc for this reaction is 0.4.
Bomai places 7mol of Ammonia NH3 in 14L flask. At equilibrium 0.2M Ammonium NH4 was found in the flask. What is the equilibrium constant Kc for this reaction?
