(e) Assertion is incorrect but reason is correct.
Answer (c). The assertion is correct, but the reason is incorrect.
The Arrhenius equation is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature, and the A factor (also known as the pre-exponential factor; can be visualized as the frequency of correctly oriented collisions between reactant particles). It provides insight into the dependence of reaction rates on absolute temperature. The expression of the Arrhenius equation is:
Rate constant determined from Arrhenius equation are fairly accurate for simple and complex molecules because only those molecules which have proper orientation during a collision (i.e., effective collision) and sufficient kinetic energy lead the chemical change.
