Interpretation:
Calculate the equilibrium constant of (Kc) given the statement of ammonia synthesis reactions.
Concept Introduction:
Equilibrium constant: Concentration of the products to the respective molar concentration of reactants it is called equilibrium constant. If the K value is less than one the reaction will move to the left side and the K values is higher (or) greater than one the reaction will move to the right side of reaction.
Equilibrium concentration: If Kc and the initial concentration for a reaction and calculate for both equilibrium concentration. The example using ICE chart and equilibrium constant and derived changes in respective reactants and products.
Haber process: This process under industrial method to producing ammonia from nitrogen and hydrogen, using (Fe) as good catalyst at highest temperature and pressure.
