The table to the right gives data for a reaction rate study of the reaction represented above. The reaction has been determined to be first order with respect to Cl2.

9. Determine the order of the reaction with respect to H2. Justify your answer.

10. Calculate the rate constant for this reaction and include the units of the k.

11. What woulr be the concentration of Cl2 at the start of trial 1?

12. In trial 3, what is the initial rate of change of H2?

The gas-phase formation of nitrogen dioxide has the following two-step mechanism.

2NO -> N2 + O2

N2 + 2O2 -> 2NO2

13. Write the balanced equation for the overall reaction.

14. Is the nitrogen atom, N2, a catalyst for the reaction or is it an intermediate? Explain.

15. Assuming the balancing coeffcients match the order for a given reactant, write the rate law/equation for this reaction
