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 1.00 x 10-1 2 8.81 x 10-2 4 7.75 x 10-2 8 6.01 x 10-2 16 3.61 x 10-2 20 2.80 x 10-2 24 2.17 x 10-2 (a) What is the average rate of reaction between 2 and 8 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 16 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.
