Explain why catalysts do not change the position of equilibrium.

In the subtopic Equilibrium and Le Chatelier's principle, this AQA A-Level Chemistry 7405 learning objective focuses on explain why catalysts do not change the position of equilibrium. It belongs to Chemical equilibria, Le Chatelier's principle and Kc, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include change, position, equilibrium, catalysts. Dynamic equilibrium. means a state in a closed system where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products Avoid the mistake of students often think that catalysts change the position of equilibrium in a reaction; instead, catalysts speed up the rate of reaching equilibrium but do not affect the equilibrium position itself. They provide an alternative pathway with a lower activation energy, allowing both forward and reverse reactions to occur more quickly without altering the concentrations of reactants and products at equilibrium For exam answers, remember that catalysts speed up the rate of reaction without being consumed, but they do not affect the position of equilibrium
