Question

The gas-phase reaction of NO with F2 to form NOF and F
has an activation energy of Ea = 6.3 kJ>mol. and a frequency
factor of A = 6.0 * 108 M-1 s-1. The reaction is
believed to be bimolecular:
NO1g2 + F21g2 ¡ NOF1g2 + F1g2
(e) Suggest a reason for the low activation
energy for the reaction.

Accepted Answer

Hi everyone for this problem. It reads the reaction given was found to have an activation energy of 5.4 kg per mole, provide an explanation for the small value of the activation energy. So we're looking at our activation energy here and we want to provide an explanation as to why is it so small? Okay. And so here, looking at our reaction, we can see that we have an electron deficient ion so we'll write electron deficient and we have an electron rich ion. Okay. So that's what we can observe in the reaction given. And these two together are going to form the product. So the combination of an electron deficient ion and an electron rich ion drives the reaction forward, which is why we have such a small activation energy. Okay, so that's the answer to this problem. I hope this was helpful.
