More about equilibria

Question 1

How does an increase in temperature affect equilibrium?

Answer 1

The equilibrium position is moved in the direction of the endothermic reaction, and the rate of reaching equilibrium is increased.

Question 2

How does an increase in pressure affect equilibrium?

Answer 2

The equilibrium position will move in the direction of the fewest molecules of gas. The rate of reaching reaching equilibrium will increase if reacting gases are present.

Question 3

How does an increase in concentration of a reacting substance affect equilibrium?

Answer 3

The equilibrium position moves in the direction away from the reacting substance. The rate of reaching equilibrium will increase.

Question 4

How does adding a catalyst affect equilibrium?

Answer 4

There will be no change in the equilibrium position, but the rate of reaching equilibrium will increase.
