What is the value of 'n' if the reaction rate of the chemical reaction A → B, is proportional to CA n and it is found that the reaction rate triples, when the concentration of 'A' is increased 9 times ?
Correct answer: A. 1/2
- A. 1/2
- B. 1/3
- C. 1/9
- D. 3
Explanation
Since r is proportional to C_A^n, tripling the rate gives 3 = 9^n. Because 9^(1/2) = 3, the reaction order is n = 1/2.
