Review Questions

These questions test vocabulary and simple concepts.

For the equilibrium reaction in Question 4, write the expression for the equilibrium constant.

(a) How would this equilibrium constant change if the total pressure on the system were doubled?

(b) How would the equilibrium constant change if the temperature were increased?

Question 4

Decomposition of ammonium dichromate is shown in the series of photos below. In a closed container this process

reaches an equilibrium state. Write a balanced chemical equation for the equilibrium reaction. How is the equilibrium affected if

(a) More ammonium dichromate is added to the equilibrium system?

(b) More water vapor is added?

(c) More chromium(III) oxide is added?
