Arrhenius equation
What does the A value in the Arrhenius equation mean? Also when do we use this equation?

Re: Arrhenius equation
A is a variable that represents the proportion of interactions that have the minimum activation energy and are in the right orientation.

Re: Arrhenius equation
You use the Arrhenius equation when you need to determine the effect of a temp change on the rate constant, which changes the overall reaction rate.

Re: Arrhenius equation
The rate constant is proportional to the reaction rate so if rate constant doubles so does the reaction rate.
Re: Arrhenius equation
A is considered the frequency factor or "pre-exponential" factor and includes the number of collisions with correct orientation. The Arrhenious equation is typically used with problems involving activation energy
