Assertion (A) Rate constant determined form Arrhenius equations are fairly accurate for simple as well as complex molecules.
Reason (R) Reatant molecules undergo chemical irrespective of their orientation during collison.

Options

A. Both assertion and reason are correct and the reason in correct explanation of assertion.
B. Both assertaion and reason are correct, but the reason does not explain essertion
C. Assertion is correct but reason is incorrect
D. Both assertion and reason are incrrect.

Answer

C

Explanation

Assertion is correct, but reason is incorrcet.
Rate constant determined form Arrhenius equation are farily accurate for simple and complex molecules because only those molecules which of have proper orientation during collision (i.e., effective collison) and sufficient kinetic lead the chemical change.
