Chapter 6: Chemical Equalibria

Question 1

What is La Chatiliers principle?

Answer 1

When a factor is changed, an equilibrium will shift to oppose that change.

Question 2

Describe what is happening when the mixture is at dynamic equilibrium

Answer 2

• rate of forward and backward reactions are equal.

- concentrations of reactant and products are not changing

Question 3

Which way will the equilibrium shift if the pressure was to increase?

Answer 3

If we increase the pressure the equilibrium will shift to the side with less gas particles.

Question 4

Which way will equilibrium shift if we reduce the pressure?

Answer 4

If we decrease the pressure the equilibrium will shift to the side with the most gas particles.

Question 5

Which way will the equilibrium shift if we increase the concentration of the reactants or products?

Answer 5

The equilibrium will shift to try to reduce the concentration.
