C13 Equilibrium

Question 1

What is a reversible reaction?

Answer 1

The reactants turn in to products and the products turn in to reactants

Question 2

What is dynamic equilibrium?

Answer 2

The point in a reversible reaction when the rate of forwards and reverse reactions are the same

Question 3

What three reaction conditions can be changed?

Answer 3

concentration
temperature
pressure

Question 4

What is Le Chatelier’s principle?

Answer 4

The position of equilibrium will shift to oppose external changes

Question 5

What is the effect of increasing the concentration of reactants on a reaction at dynamic equilibrium?

Answer 5

Favours the forward reaction

Question 6

What is the effect of decreasing the concentration of products on a reaction at dynamic equilibrium?

Answer 6

Favours the forward reaction

Question 7

What is the effect of increasing pressure on a reaction at dynamic equilibrium?

Answer 7

Favours the reaction that leads to the fewest molecules

Question 8

What is the effect of decreasing pressure on a reaction at dynamic equilibrium?

Answer 8

Favours the reaction that leads to the most molecules

Question 9
