1) How do you know if a system reaches its equilibrium or not?

2) What is a must condition for a system to have equilibrium?

3) For a reaction aA + bB ïƒ³ dD + eE, write the equilibrium-constant expression.

4) For a reaction in (3), and when all the components are gasses, write its equilibrium constant in terms of pressure, Kp

5) Write Kp using Kc

6) When does Kp equal to Kc?

7) For a reaction in (3), if the Kc is greater than 1, what does it tell you about the equilibrium?

8) For a reaction in (3), if the Kc is smaller than 1, what does it tell you about the equilibrium?

9) What do Kc and Kp depend on? ( stoichiometry, partial pressures and concentrations are excluded in here)

10) Why is it possible to add up different balanced chemical equations to form a particular chemical equation and calculate its Kc from multiplying the Kc values of the different equations?

11) For the physical states, solid, liquid, aqueous solution, and gas, which are not included in the equilibrium-constant expressions?

12) Write the 5 steps to calculate Kc when not all equilibrium concentrations are available.

13) What is the difference between Kc and Qc?

14) How can you use Kc and Qc to predict the direction of equilibrium mixture to move?

15) What is Le Chateliers principle?
