3.1.6 Chemical Equilibria

Question 1

What do all reversible reactions reach?

Answer 1

Dynamic equilibrium

Question 2

What are the features of dynamic equilibrium? [2]:

Answer 2

• Forward and backwards reactions are occurring at the same rate
• The concentrations of reactants and products stays the same

Question 3

What does dynamic equilibrium mean?

Answer 3

Both forward and backwards reactions are occurring simultaneously

Question 4

What does Le Chatelier’s principle state?

Answer 4

If an external condition is changed the equilibrium will shift to oppose the change

Question 5

What is the effect of temperature on equilibrium?

Answer 5

If the temperature is increased the equilibrium will shift to oppose this change, favouring the endothermic reaction to reduce the temp by absorbing heat and vice versa

Question 6

What is low temperature’s effect at dynamic equilibrium? [2]:

Answer 6

• May give a higher yield of product

- Slows rates of reaction
