For a bimolecular elementary reaction between A and B, the rate of reaction is expressed as
$rate=P.Z_{AB}e^{(-\frac{E_a}{RT})}$
Identify the terms $P, Z_{AB}$ and $E_a$, involved in this expression, respectively
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Probability factor, collision frequency, Activation energy
For a bimolecular elementary reaction according to collision theory:
$\text{rate} = P \cdot Z_{AB} \cdot e^{-E_a/RT}$
Where:
- P = probability (steric) factor
- $Z_{AB}$ = collision frequency between A and B
- Ea = activation energy
