The rate of the chemical reaction A → B doubles as the concentration of A i.e.., CA is doubled. If rate of reaction is proportional to CA n, then what is the value of n for this reaction ?
Correct answer: C. 1
- A. 0
- B. 0.5
- C. 1
- D. 2
Explanation
For r proportional to C_A^n, doubling concentration gives 2^n = 2. Hence n = 1, so the reaction is first order in A.
