For a homogeneous reaction of nth order, the dimension of the rate constant is given by_________________?
Correct answer: B. (Concentration)1 - n/(time)
- A. 1/(time)n
- B. (Concentration)1 - n/(time)
- C. (Concentration)n - 1/(time)
- D. None of these
Explanation
For an nth-order rate law, rate=kC^n, the units of k must make the result concentration per time. Therefore k has dimensions (concentration)^(1-n)/time, as given in option B.
