14.4 Collision Theory and the Arrhenius Equation | General Chemistry 

Chad provides a comprehensive lesson on Collision Theory and the Arrhenius Equation. Collision Theory is first described showing the three requirements that must be met for a chemical reaction to occur, and showing conceptually why reactions go faster at higher temperatures. Next the Arrhenius equation is presented which shows the dependence of the rate constant (k) on the activation energy and the temperature. An Arrhenius plot is shown including how it can be used to calculate the activation energy of a reaction as well as the Arrhenius constant. Finally, the lesson is concluded with a sample calculation of how to use the Arrhenius equation to calculate the rate constant at one temperature having been provided the value at a second temperature.
