The initial rates listed in the table were determined for thethermal decomposition of azomethane (CH3N=NCH3):
CH3N=NCH3 (g) → C2H6 (g) + N2 (g)
Experiment Initial [CH3N=NCH3]M
Initial rate of decomposition
of [CH3N=NCH3] (M/s)
1 2.4 x 10-2 6.0 x 10-6
2 8.0 x 10-3 2.0 x 10-6
(a) What is the rate law? (2 mark)
(b) What is the value of the rate constant for the decomposition reaction?
(c) Calculate the percentage of azomethane that it will decomposein 10 minutes if the initial concentration of azomethane is equal to1.5×10-2M.
