The reaction A → B + C is known to be first order in A. Below are data showing the concentration of A as a function of reaction time.

Time, h	[A], M
0.5	5.00 x 10^-2
1	4.51 x 10^-2
2	4.06 x 10^-2
3	3.30 x 10^-2
4	2.18 x 10^-2
5	1.77 x 10^-2
6	1.44 x 10^-2

(a) What is the average rate of reaction between 0.5 and 2 h? Report the units as well as the numbers.

(b) Plot the data above, showing the concentration of A as a function of the time. From your graph, determine the instantaneous rate of reaction at 4 h. Report the units as well as the numbers.

(c) Plot ln [A] versus time. Estimate the rate constant for this first-order reaction from your graph. Report the units as well as the numbers.
