Question

In a bimolecular reaction, the steric factor P was experimentally determined to be 4.5. The correct options among the following is (are):
A. The value of frequecny factor predicted by Arrhenius equation is higher thatn that determined experimentally
B. The activation energy of the reaction is unaffected by the value of the steric factor
C. Since P=4.5 the reaction will not proceed unless an effective catalyst is added
D. Experimentally determined value of frequecny factor

Answer 1

Correct Answer - B::D
Activation energy of a reacton does not depend on the value of steric factor
`Pgt` 1 shows that `A_("cal")ltA_("exp")`.
Here `A_("cal")` = Calcualated frequency factor using Arrhenius equation
`A_("exp")` = Experimentally determined fequency factor
