Use Le Chatelier's principle to predict the effect of pressure changes.

In the subtopic Equilibrium and Le Chatelier's principle, this AQA A-Level Chemistry 7405 learning objective focuses on use Le Chatelier's principle to predict the effect of pressure changes. 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 Le Chatelier, pressure. 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 increasing pressure will always shift the equilibrium to the right, regardless of the reaction; instead, to fix this, remember that increasing pressure shifts the equilibrium towards the side with fewer moles of gas. Always analyze the balanced equation to determine the effect of pressure changes For exam answers, when pressure is increased in a closed system at equilibrium, the system will shift to the side with fewer moles of gas
