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 experimentallyB. The activation energy of the reaction is unaffected by the value of the steric factorC. Since P=4.5 the reaction will not proceed unless an effective catalyst is addedD. Experimentally determined value of frequecny factor |

Answer» 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 |
