The value of ‘n’ for a chemical reaction A → B, whose reaction rate is → CA n, will be _______________ if the rate of the reaction increases by a factor of 8, when the concentration of is doubled?
Correct answer: D
Explanation
The rate law is Rate = k[A]^n. If the rate increases by 8 when [A] doubles (factor of 2), then $2^n = 8$, so n=3.
