since

P = 4.5

, the reaction will not proceed unless an effective catalyst is used

Solution

The correct options 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 Arrheneius equation
Activation Energy does not depend on the steric factor.
The steric factor which is 4.5 is much higher than Arrhenius factor for the frequency factor because
$P = \frac{F r e q u e n c y F a c t o r}{A r r h e n i u s F a c t o r}$
