Chemical Equilibrium:• Chemical equilibrium is a state where the rate of forward reaction is equal to the rate of backward reaction.• This state is reached when the concentration of reactants and products are constant, and the reaction proceeds at a steady rate.• Dynamic equilibrium refers to the changing conditions of a system in equilibrium, which results in a shift of the position of equilibrium.Le Chatelier's Principle:• Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.• The principle applies to both reversible and irreversible reactions.• Factors that can affect chemical equilibrium include temperature, pressure, concentration of reactants, and the presence of catalysts or inhibitors.Haber Process:• The Haber process is a chemical reaction that produces ammonia from nitrogen and hydrogen.• The reaction is exothermic, so a low temperature will encourage the forward reaction and more ammonia at equilibrium.• An increase in pressure will encourage the smaller volume of products, which is to the right in this case.• A high pressure of 200 atmospheres is normally used in the Haber process.Catalysts:• Catalysts have no effect on the amount of products obtained at equilibrium.• They catalyze equally the forward and backward reactions.• Without a catalyst, the reactions in both the forward and backward directions will be extremely slow.• Catalysts help the reaction reach equilibrium much more quickly.
