the variable A

[bellaha4F]

i don't quite understand what the variable "A" in the Arrhenius Equation means (k=Ae^-Ea/RT), can someone please explain it to me, thanks!!

The variable A is the frequency or the pre-exponential factor.

[Jasmine W 1K]

A is the frequency factor or pre-exponential factor. It includes the number of collisions with the correct orientation.

[Lauren Stack 1C]

A was described in class as the frequency factor or pre-exponential factor (includes # of collisions with correct orientation)

[Sofia Barker 2C]

In the Arrhenius equation, A is a constant that varies for different reactions. It is called the frequency factor or pre-exponential factor and it is simply a value that takes into account the frequency of collisions when determining the rate constant for a specific reaction.
