Rates of Reactions The effects of a variety of variables, including concentration, temperature and catalysts, on reaction rate are shown.
Kinetics

Iodine Clock Reaction A solution of hydrogen peroxide and sulfuric acid is added to a solution containing iodide ion, thiosulfate ion, and starch. After some time the dark blue color of a triiodidestarch complex is observed. The influences of initial reactant concentrations on the reaction time are examined, as are the influence of volume and temperature.

Kinetics : CompareEnergyProfile (11 Variations)
Consider the following reactions that take place at the same temperature, begin with the same molar concentrations, and whose energy profiles are presented below:
Kinetics

Kinetics : ArrheniusTemp (3 Variations)
The activation energy for the isomerization of cyclopropane to propene is 274 kJ/mol. By what factor does the rate of reaction increase as the temperature rises from 500^{o}C to 550^{o}C assuming all else remains constant? (R = 8.314 J/mol k)
Hint: This is asking for the ratio of rates which is proportional to the ratio of the rate constants, all else being equal.

Kinetica; An Excel program to Stimulate or Analyze Kinetic Data Leonel Vera, Pedro Ortega, Miguel Guzmán The Excel spreadsheet Kinetica both simulates and analyzes kinetic data for simple rate equations of the form:  d[A]/dt = k [A]^n Instructors or students can generate simulated kinetic data using parameters they specify, or using parameters randomized by Kinetica. The data set that is generated may then be exported for use in exercises, homework, and exams, or may be analyzed directly within Kinetica. A kinetics data set may also be imported from an external source into Kinetica for analysis.
Kinetics

An Excel Program to Study FirstOrder Kinetics Ken Muranaka User data can be analyzed to determine what parameter values of the first order rate expression give the closest fit, or data can be generated using userinput values of the rate parameters and random noise levels. Statistical characterizations such as confidence limits and variance are calculated.
