1. Use equation 9 to predict the initial rate if [NO]inital = 0.03 M and [H2]inital = 0.15M.

• What would happen to the initial rate of the reaction if [NO]inital = 0.60 M and [H2]inital = 0.15 M instead. Does your result make sense in terms of the order of the reaction?

2. Assuming the concentration are expressed in moles per liter and time in seconds, what are the units of the rate constant, k, for an overall first order rate law? Show your work.

• What are the units of k for an overall second order rate law? Show your work.

• Using these two rate constants as examples, write a general rule to explain how the units of the rate constant depend on the overall order of the rate law.

3. Write the general form of the rate law for the reaction in Equation 9.
