Kinetics : ArrheniusActEnergy (4 Variations)
The rate constant for the first-order dehydration of tert-butyl alcohol at 500^{o}C is 1.20 x 10^{ -4 } s^{ -1}. The rate constant for this process at 600^{o}C is 6.80 x 10 ^{ -3} s^{ -1}. Calculate the activation energy for this reaction in kJ/mol. (R = 8.314 J/mol K)

Reaction Order Ambiguity in Integrated Rate PlotsJoe Lee This article provides a theoretical and statistical justification for the necessity of monitoring a reaction to a substantial fraction of completion if integrated rate plots plots are to yield unambiguous orders. Lee, Joe. J. Chem. Educ.2008, 85, 141.

Using a Graphing Calculator To Determine a First-Order Rate Constant: Author ReplyJosé E. Cortés-Figueroa When technology is used to help with mathematical calculations, the emphasis must be on the concepts being learned rather than simply the procedures. In our approach we are attempting to help students learn more about the concept and also to attain data analysis skills they will need in the future. Cortés-Figueroa, José E. J. Chem. Educ.2004, 81, 485.

Using a Graphing Calculator To Determine a First-Order Rate ConstantTodd P. Silverstein The authors use the graphing calculator to estimate the infinity reading from linearized kinetics data, and then they use linearized semi-log data to determine the first-order rate constant.
