HI
While working on some chemical kinetics problems, I came across the statement, the fraction of activated molecules is [itex]10^{-15}[/itex] in a problem where some other constants were also provided and the half life was to be found (for a first order reaction). My specific query is:
Is this fraction equal to the probability factor in the Arrhenius Equation? That is, is this equal to P where
[tex]k = APe^{-E_{act}/RT}[/tex]
where k = rate constant, A = frequency factor, P = probability factor, [itex]E_{act}[/itex] = activation energy and T = absolute temperature?
Or is it something else?
Thanks and cheers
