Equilibrium

Question 1

State the definition of a dynamic equilibrium.

Answer 1

Equilibrium that exists in a closed system when:
- the rate of the forward reaction is equal to the rate of the backward reaction.
- the concentrations of reactants and products remain constant

Question 2

What is the reactant effect?

Answer 2

If reactants are added (or products removed), equilibrium shifts right in the forward direction.

Question 3

What is the product effect?

Answer 3

If products are added (or reactants removed), equilibrium shifts left in the backward direction.

Question 4

If equilibrium lies to the right, what does it mean?

Answer 4

There’s a greater concentration of products than reactants.

Question 5

If equilibrium lies to the left, what does it mean?

Answer 5

There’s a greater concentration of reactants than products.

Question 6

What happens if you add a catalyst?

Answer 6

• less activation energy needed
• acts of both forward and backward reaction
• doesn’t affect equilibrium
• only affects rate which reactants/products are produced
