1. The rate law expresses the relationship between the rate of a reaction and the   of the reactants.

2. The   of a reaction cannot be determined from the balanced chemical equation alone; it must be determined experimentally.

3. For a reaction A + B → C, if the rate law is Rate = k[A][B]^2, the overall order of the reaction is  .

4. Which of the following statements about the rate constant (k) is true?

5. Consider the reaction: 2NO(g) + O2(g) → 2NO2(g). If the rate law for this reaction is determined to be Rate = k[NO]^2[O2], what is the order of the reaction with respect to NO?

6. For the same reaction in question 5, what is the overall order of the reaction?

7. The exponents in a rate law are always equal to the stoichiometric coefficients in the balanced chemical equation.

8. The following data were obtained for the reaction: A + B → C

Experiment | [A] (M) | [B] (M) | Initial Rate (M/s) ---|---|---|--- 1 | 0.10 | 0.10 | 4.0 x 10^-5 2 | 0.20 | 0.10 | 8.0 x 10^-5 3 | 0.10 | 0.20 | 1.6 x 10^-4

Determine the rate law for this reaction.
