The reaction is thought to follow second order kinetics which follows the relationship 1/[A]=1/[A]0+kt where [A] is the molarity at time, t, and [A]0 is the initial concentration. k is the rate constant. In this case the following data was obtained. Time (min) [A] (molarity) 10 0.51 20 0.42 30 0.36 40 0.31 Analysis a. Transform the data given above so that it would show linear dependence in the case of a second order reaction. b. Make a plot of the data with the appropriate variables as x and y consistent with the second order equation given. c. From the plot, draw by eye a best fit through the data and estimate the slope and y-intercept of the best linear fit of the data. Be sure to include units! d. Using linear regression calculations, determine the slope and the y-intercept of the best fit of the data. Be sure to include units! e. Do the two determinations of linear relationship in the data agree? f. From your analysis, determine best values of k and [A]0.
