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

According to Arrhenius equations
$\mathrm{k}={\mathrm{Ae}}^{-{\mathrm{E}}_{\mathrm{a}}/\mathrm{RT}}$
Where, A=Frequency factor
Taking into account orientation factor,
$\mathrm{P}=\frac{\mathrm{A}}{\mathrm{Z}}\text{ or }\mathrm{A}=\mathrm{PZ};\mathrm{k}={\mathrm{PZe}}^{-\mathrm{Ea}/\mathrm{RT}}$
Where, P=steric factor, Z=collision frequency
The value of steric factor lies between 0 and 1 predicted by Arrhenius equation. Thus, the experimentally determined value of frequency factor is higher than that predicted by Arrhenius equation.Thus, (b) is correct
