Question

In the given expression $r=\rho Z_{AB}{e}^{\frac{-Ea}{RT}}$
Which term is called the steric factor:

• A. $Z_{AB}$
• B. $\rho$
• C. $e^{\frac{-Ea}{RT}}$
• D. $\rho Z_{AB}$

Answer 1

The correct option is B $\rho$

This is a generalised rate expression of a chemical reaction that we get by the collision theory. Here, $\rho$ denotes the steric factor.
