An Intiative by Sri Chaitanya
a
The activation energy of the reaction is unaffected by the value of the steric factor
b
Experimentally determined value of frequency factor is higher than that predicted by Arrhenius equation
c
The value of frequency factor predicted by Arrhenius equation is higher than that determined experimentally
