3.The
initial rate of the reaction between the gases NO and H2 was measured
in a series of experiments at a constant temperature and the following rate
equation was determined.
rate
= k[NO]2[H2]
(a)Complete the table of data below for the
reaction between NO and H2

b.Using the data from experiment 1, calculate a value for the rate constant, k, and state its units.
rate = k [CH3COCH3][H+]
•Use these data to calculate a value for the rate constant and deduce its units.
