Raiisng the concentration of a particular reactant by a factor of `5` increases the reaction rate `25` times. What is the kinetic order of this reactant?

Text Solution

Verified by Experts

`r prop [A]^(a)` …(i)
`25r prop [5A]^(a)` …(ii)
Dividing equation (ii) by (i),
`(25 r)/(r ) prop ([5A]^(a))/([A]^(a))`
`a = 2`, second order reaction
