The rate of combination of simple alkyl free radicals:

A

increases with increase in temperature

B

dependent of temperature

C

decreases with increase in temperature

D

altogether different for different reactions and independent of temperature

Text Solution

Verified by Experts

`r = K[A]^(n)` and `K = A e^(-E_(a)//RT). E_(a) = 0` for free radical combination. K is constant with T.
