WebThe Arrhenius equation is k = Ae^(-Ea/RT), where A is the frequency or pre-exponential factor and e^(-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T.This equation can be used to understand how the rate of a chemical … WebTheoretical Kinetics Problem: Variable components of Arrhenius equation (Ea, A) are not based in chemical theory; Nevertheless, equation works fantastically. Challenge: How do we reproduce form of Arrhenius equation using theory instead of just observation? In other words, how do we express E a and A in terms of real physical parameters?

So we have 3.221 times 8.314 and then we need to divide that by 1.67 times 10 to the -4. And so we get an activation energy of approximately, that would be 160 kJ/mol. We need our answer in kJ/mol and not J/mol, so we'll say approximately 160 kJ/mol here. elk grove california water meter
