14Dynamic Equilibria Equilibrium ConstantsMedium1 mark
Nitrogen and hydrogen react to form ammonia in a reversible reaction. A sealed reaction vessel contains a mixture of nitrogen, hydrogen and ammonia at equilibrium at 500 K. This mixture is put into a much larger sealed vessel. The temperature in this vessel is maintained at 300 K. Which prediction can be made with certainty?
