Question

In a bimolecular reaction, the steric factor $P$ was experimentally determined to be $4.5.$ The correct option(s) among the following is(are)

• 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. Since P = 4.5, the reaction will not proceed unless an effective catalyst is used
• D. The value of frequency factor predicted by Arrhenius equation is higher than that determined experimentally

Answer 1

Answer: (B)

Experimentally determined value of frequency factor is higher than that predicted by Arrhenius equation

Answer 2

[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
