Equilibrium

Question 1

What is dynamic equilibrium?

Answer 1

A state in a reversible reaction where the forward and backward reactions occur at the same rate, and the concentrations of reactants and products remain constant.

Question 2

What are the conditions required for equilibrium?

Answer 2

A closed system and constant temperature.

Question 3

What is Le Chatelier’s Principle?

Answer 3

If a change is made to a system at equilibrium, the system will shift to oppose the change and restore equilibrium.

Question 4

How does increasing the concentration of a reactant affect equilibrium?

Answer 4

The equilibrium shifts to the right

Question 5

How does increasing the pressure affect equilibrium in a gaseous system?

Answer 5

The equilibrium shifts to the side with fewer gas molecules.

Question 6

How does increasing temperature affect an exothermic reaction at equilibrium?

Answer 6

The equilibrium shifts to the left

Question 7

How does increasing temperature affect an endothermic reaction at equilibrium?

Answer 7

The equilibrium shifts to the right

Question 8

What is the effect of a catalyst on equilibrium?

Answer 8

It speeds up both the forward and backward reactions equally but does not affect the position of equilibrium.
