Equilibrium 0.0 / 5 ? ChemistryEquilibriaASAQA Created by: jatyizationCreated on: 03-02-14 18:44 What is dynamic equilibrium? The composition of a reaction mixture does not change because both foreword and backward reactants are proceeding at the same time. 1 of 9 What are the rules for equilibrium? Closed system; Can be approached from any direction; dynamic process; achieved when macroscopic properties are same 2 of 9 Which way does equilibrium move if products increase? Equilibria moves to the right 3 of 9 Which way does equilibria move if reactants increase? Equilibrium moves to the left 4 of 9 What is Le Chateliers principle? If system at equilibrium is disturbed, the equilibrium moves in the direction that tends to reduce disturbance. 5 of 9 how does pressure effect equilibrium? Equilibrium will move to the side with the least molecules 6 of 9 How does concentration effect equilibrium? Equilibrium moves to the side that reduces concentration of reactants 7 of 9 How does temperature effect equilibrium? Equilibrium moves to the endothermic side of the reaction to cool the system down 8 of 9 How does catalyst effect equilibrium? no effect on position of equilibrium as it effect both sides equally, however the reaction gets to equilibrium faster. 9 of 9
