Arrhenius Equation.

[Jennifer Torres 2L]

How would one know in which case to use the Arrhenius equation?

[Alexa Tabakian 1A]

You use this equation when you either have activation energy or need to find it.

[Sam Joslyn 1G]

The Arrhenius equation would be used in any circumstance in which you are required to find the rate of a reaction from its activation energy and frequency factor. It can also be used to compare the rate of a reaction at different temperatures with the equation ln(k₂/k₁)=(E_a/R)*(1/T₁-1/T₂)

The Arrhenius equation can be used to determine the effect of a change of temperature on the rate constant, and thus on the rate of the reaction. The equation being k=Ae^-(Ea/RT)

[Lorena Zhang 4E]

Basically, you will use the equation to solve for the rate, temperature, or activation energy. Also, you may use the equation to compare the reaction under different temperature. When using Arrhenius equation, typically all but one conditions would be given.
