5. The reaction AB+C is known to be first order in A. Below are data showing the concentration of A as a function of reaction time. (a) What is the average rate of reaction between 2 and 8h ? 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 16h. 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
