arrhenius equation
What is the value of A exactly? What does it stand for/mean in terms of rates and the rate constant?
Re: arrhenius equation
A is the pre-exponential factor. It is the fraction of molecules that would react if the activation energy was zero (if Ea is 0, e^0/RT would be 1 so your arrhenius equation would be k=a).
A is usually determined with experimental data, since it's different for different reactions.
