JEE Main Chemistry question

Assertion: As the temperature increases, rate of reaction increases. Reason: The rate of reaction increases due to increase in collision frequency and shortening of mean free path.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Raising the temperature increases the average molecular speed, which shortens the mean free path and raises the frequency of molecular collisions; since a larger fraction of these more frequent
