Equilibrium

Question 1

What is dynamic equilibrium?

Answer 1

The rate of the forward recruiting is equal to the rate of the backward reaction and the concentrations of reactants and products remains constant

Question 2

What is a closed system?

What happens to the equilibrium of products are added?

Answer 2

When no more reactants can be added or removed from the reaction mixture.

If the reactants are added or if products are removed, the equilibrium position is then displaced

Question 3

State Le Chatelier’s principle was

Answer 3

A system at equilibrium will react to oppose any change imposed upon it

Question 4

Which three factors effect the position of equilibrium

Answer 4

Concentration
Temperature
Pressure

Question 5

What happens if you add a catalyst?

Answer 5

The rate of reaction is increased but there is no effect on the yield as it increases both forward and backward reactions equally

Question 6

If a question mentions time taken to reach equilibrium what is it asking and what should you include in your answer

Answer 6

Rate of reaction

Answers should reference kinetic theory and collisions, regardless of position of equilibrium
