Equilibrium

Question 1

What is a reversible reaction?

Answer 1

When the reactants turn into products and the products can turn back into the reactants.

Question 2

What is a dynamic equilibrium?

Answer 2

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

Question 3

What are the three reaction conditions that can be changed?

Answer 3

• Concentration
• Temperature
• Pressure

Question 4

What is Le Châtelier’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 decreasing 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 increasing temperature on a reaction at dynamic equilibrium?

Answer 8

Favours the endothermic reaction.

Question 9

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

Answer 9

Favours the exothermique reaction.
