If a change is made to a system at equilibrium, what will happen according to Le Chatelier’s Principle?Nothing will happenThe backwards reaction will always be favouredThe system will respond either way to counteract the changeThe forwards reaction will always be favoured2In the reaction A + B ⇌ C + D, what happens to the amounts of the reactants and products if the concentration of D is increased?A, B and C increase; D decreasesA, B and C decrease; D increasesA and B decrease; C and D increaseA and B increase; C and D decrease3For a system at equilibrium, which of the following statements is correct?Increasing the temperature always favours the backwards reactionIncreasing the temperature always favours the exothermic reactionIncreasing the temperature always favours the endothermic reactionIncreasing the temperature always favours the forwards reaction4For the following equilibrium 2SO2(g) + O2(g) ⇌ 2SO3(g), what will happen to the concentrations of each gas if the pressure is increased?SO2, O2 and SO3 will all increaseSO2, O2 and SO3 will all decreaseSO2 and O2 will increase; SO3 will decreaseSO2 and O2 will decrease; SO3 will increase

According to Le Châtelier's principle, what would happen to a system at equilibrium if more of one compound in a reaction were added?A.Nothing would change at equilibrium.B.The equilibrium constant would change.C.The system would remain stressed.D.All concentrations would change.SUBMITarrow_backPREVIOUS

What does Le Châtelier's principle predict will happen to a system if equilibrium is upset in the following ways? (2 points) Additional reactant is added. (0.5 point) Additional product is added.

What does Le Châtelier's principle state?A Equilibrium cannot be re-established once it is disturbed.B A system at equilibrium will remain at equilibrium forever.C A system will react to re-establish equilibrium if it is disturbed.D A reaction will proceed to completion if equilibrium is disturbed.

For a reaction in equilibrium, if the concentration of one of the reactants is increased, how will the equilibrium position respond?Select one:a.The reaction will stop completely.b.The equilibrium position will shift toward the reactant side.c.The equilibrium position will remain unchanged.d.The equilibrium position will shift toward the product side.
