Question 27

Rates of Reaction

If the rate law obtained for a given reaction is rate = k [X]n [Y]m, what is the overall order of the reaction?

  1. A.nm
  2. B.n/m
  3. C.n + m
  4. D.n − m
Show the answer and explanation

Answer: C (n + m)

Explanation

The overall order is the sum of the powers of the concentrations in the rate law: n + m.
