Azomethane decomposes into nitrogen and ethane at elevated temperature:
h3c_n=n_ch3 _ n2 + c2h6
a chemist studying this reaction at 300ác begins an experiment with an azomethane concentration of 4.25 mm and obtains the following data:
time(s) 100 150 200 250 300
[azomethane] (mm) 3.29 2.90 2.55 2.25 1.98
calculate the rate constant. give an answer with concentration units of molarity and time units of seconds.
