Azomethane decomposes into nitrogen and ethane at high temperatures according to the following equation:

The following data are obtained in an experiment:

(a) By plotting the data, show that the reaction is first-order.

(b) From the graph, determine k.

(c) Using k, find the time (in hours) that it takes to decrease the concentration to 0.100 M.

(d) Calculate the rate of the reaction when
