Give me some responses to the questions below and I'll give you some extra credit.


Laboratory Section:

1. Kc for the following reaction;

NOBr(g) NO(g) + 1/2Br2(g)

is 0.079. Calculate Kc for the following reaction;

2NOBr(g) 2NO(g) + Br2(g)

2. Kc 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;












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.
