The rate constant of a reaction is measured at different temperatures. a plot of the natural log of the rate constant as a function of the inverse of the temperature (in kelvins) yields a straight line with a slope of -8100 k−1 . you may want to reference (page 644) section 14.5 while completing this problem. part a
