The rate law for the reaction below is given by the expression k A [ B ] A + B → P r o d u c t If the concentration of B is increased from 0 . 1 to 0 . 3 mol , keeping the value of A at 0 . 1 mol , the rate constant will be:

Options

  1. A3 k
  2. B9 k
  3. Ck / 3
  4. Dk

Correct answer

D. k

Step-by-step solution

Rate constant is independent of concentration. It depends only on temperature. But the rate of the reaction increases by three times as the order of the reaction is one.
