Question 14

Rates of Reaction

The rate law obtained for a given reaction is expressed as r = K [X]n [Y]m. The overall order of the reaction becomes.

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

Answer: D (n+m)

Explanation

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