Reaction Order Ambiguity in Integrated Rate Plots Joe 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.

Using a Graphing Calculator To Determine a First-Order Rate Constant: Author Reply José 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.

Using a Graphing Calculator To Determine a First-Order Rate Constant Todd 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.

Don't Be Tricked by Your Integrated Rate Plot: Reaction order Ambiguity Sue Le Vent
Integrated rate equations (for constant reaction volume) may be given in terms of relative reactant concentration, C (= concentration/initial concentration) and relative time, T (= time/half-life); in these forms, the equations are independent of rate constants and initial concentrations.

Curve Fitting: An Alternative Approach to Analyzing Kinetic Data in Introductory Chemistry Coleman, William F.
183. The availability of high quality software for performing nonlinear curve fitting on microcomputers allows students to take an alternative approach to data analysis, one that concentrates on functional forms that may be more natural than some of the algebraic machinations necessary to render relationships into linear forms. An example of the application of such an approach to the analysis of kinetic data is presented in this paper.

A statistical note on the time lag method for second-order kinetic rate constants Schwartz, Lowell M.
A clever method for finding second-order kinetic rate constants by using a time lag method that avoids direct measurement of the end point reading P(infinity) can easily be programmed.
