Laboratory Section:

1. K_c for the following reaction;

NOBr(g) NO(g) + 1/2Br₂(g)

is 0.079. Calculate K_c for the following reaction;

2NOBr(g) 2NO(g) + Br₂(g)

2. K_c for the following reaction;

3O₂(g) 2O₃(g)

is 1.7 x 10^-56 at 25 degrees Celsius. At equilibrium the [O₂] = 7.2 x 10^-3 M, calculate what the [O₃] must be at equilibrium.

3. In class we investigated the reaction between A₂ and B₂. Consider the following table;

	[A₂]	[B₂]	[AB]
Initial	45	45	0
Change
Equilibrium			60

Complete the remaining entries in the table.

4. Calculate K for the reaction in Q3.

5. Is there anything about the reaction or the questions that you feel you do not understand? List your concerns/questions.
