Paper 2- Unit 6b Equilibrium

Question 1

What a dynamic equilibrium?

Answer 1

when the forward and backward reaction

are happening at the same time

at the same rate

with constant concentration of the reactants and products

Question 2

What is le chatilliers principle?

Answer 2

If you change the conditions of an equilibrium

the reactions opposes the change

Question 3

If the temperature of an equilibrium system increases

Answer 3

the reaction favours the endothermic reaction

Question 4

If the temperature of an equilibrium system decreases

Answer 4

the reaction favours the exothermic reaction

Question 5

If the pressure of an equilibrium system increases

Answer 5

the reaction favours the side with the least mole of gas

Question 6

If the pressure of an equilibrium system decrease

Answer 6

the reaction favours the side with the most mole of gas

Question 7

Catalysts effect on equilibrium

Answer 7

No effect on position

rate of both the backward and forward reaction are both increased

reaches equilibrium quicker
