For the elementary reaction M `rarr` N, the rate of disappearance of M increases by a factor of 8 upon doubling the concentration of M. The order of the reaction with respect to M is:

A

4

B

3

C

2

D

1

Text Solution

Verified by Experts

Consider, rate `(r) = K[M]^(n)` where n is order of reaction `(r_(1))/(r_(2)) = (1)/(8)= ([M]^(n))/([2M]^(n)) rArr n = 3`
