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. 3
- A. 0
- B. 1
- C. 2
- D. 3
Explanation
With rate proportional to C_A^n, doubling concentration changes the rate by 2^n. Since the rate becomes eight times larger and 8 = 2³, the reaction order is 3.
