a. The dissociation of molecular iodine into iodine atoms is represented as: I2 (g) <==> 2I (g)

At 1000 K, the equilibrium constant Kc for the reaction is 3.80 x 10-5. Suppose we start with 0.0456 mole of I2 in a 2.30 L flask at 1000 K. What are the concentration of the gases at equilibrium? 

b. Circle the correct statement(s) below that correspond to a major reaction (There may be more than one correct answer. You must choose all the correct answers for full marks.)

At 1000 K, the equilibrium constant Kc for the reaction is 3.80 x 10-5. Suppose we start with 0.0456 mole of I2 in a 2.30 L flask at 1000 K. What are the concentration of the gases at equilibrium?

1. (i) The position of the equilibrium lies to the left
2. (ii) Lots of product is formed
3. (iii) Very little reactant is used up
4. (iv) Value of Kc is very large
5. (v) Value of Kc is very small
