2.3 The effect of changing conditions on equilibria 0.0 / 5 ? ChemistryEquilibriaA2/A-levelAQA Created by: Isabel CookeCreated on: 08-02-14 18:25 What is Le Chatelier's principle? When a system at equilibrium is disturbed, the equilibrium moves in the direction so as to reduce disturbance. 1 of 6 How do catalysts affect Kc? They have no effect as they affect forward and backward reactions equally. 2 of 6 If Kc is bigger than 1, are there more reactants or products? Products. 3 of 6 How does increasing the number of reactants affect Kc? Kc increases. 4 of 6 How would a decrease in temp in exothermic reaction affect Kc? Kc increases. 5 of 6 How would a decrease in temp endothermic reaction affect Kc? Kc decreases. 6 of 6
