In the following question, a statement of Assertion The answer is the option (i) followed by a statement of Reason (R) is given. Choose the correct option out of the following choices:

Assertion The answer is the option (i): Rate constants determined from Arrhenius equation are fairly accurate for simple as well as complex molecules.
Reason (R): Reactant molecules undergo chemical change irrespective of their orientation during collision.

(i) Both Assertion and Reason are correct and the reason is the correct explanation of Assertion.
(ii) Both assertion and reason are correct but Reason is not the correct explanation of Assertion
(iii) Assertion is correct but Reason is incorrect.
(iv) Both Assertion and Reason are incorrect.
(v) Assertion is incorrect but Reason is correct.

Answers (1)

The answer is the option (iii). The criteria for an effective collision and rate of chemical reaction is determined together by activation energy and proper orientation of molecules in the collision theory.
