Equilibrium

Question 1

What is equilibrium constant affected by?

Answer 1

Temperature

Question 2

What does the Le Chatelier’s principle state?

Answer 2

It states that if an external condition changes, the equilibrium will shift to oppose the change.

Question 3

What is a heterogeneous system?

Answer 3

It is a system where not all chemicals are in the same phase.

Question 4

What is a Homogeneous system?

Answer 4

It is a state where all chemicals are in the same phase.

Question 5

What does equilibrium constant require?

Answer 5

dynamic equilibrium

Question 6

What is a closed system?

Answer 6

A system where there is no heat exchange occurring between the system and its surroundings. No matter can enter or exit the system.

Question 7

What are the features of dynamic equilibrium?

Answer 7

• both forward and backward reactions are happening
• rate of forward backward reactions are the same
• reversible reaction
• closed system
• concentration of reactants and products are constant, not the same

Question 8

Does catalysts have effect on equilibrium position and yield?

Answer 8

They will have no effect in equilibrium position and yield
BECAUSE they can only increase the rate of reaction of both forward and backward reactions equally
