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.

An alcohol thermometer makes use of alcohol's changing in order to measure temperature. as the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
