I need help understanding the meaning and units involved in the Arrhenius Law equation.
Assuming a first order reaction:
k = Ae^-Ea/RT
1) Can this be re-written as: logk = -Ea/RT + constant ? What is the constant?
2) In either case:
a) How do I determine or choose the activation energy Ea? Where would I find this value?
b) Similarly, how would I determine the frequency factor A???
c) Is it assumed that the exponent e value is really power 10^-Ea/RT?
I just want to know how I actually plug in values in this equation if I am trying to determine the difference in the rate reaction at temp 1060 degrees K and 673 degrees K
Is k ultimately in units of 1/sec??© BrainMass Inc. brainmass.com March 4, 2021, 7:58 pm ad1c9bdddf
Arrhenius Law and its equation are explained. The expert examines first order reaction kinetics.
