Consider an elementary reaction A ( g )+ B ( g ) C ( g )+ D ( g ) If the volume of reaction mixture is suddenly reduced to 1 3 of its initial volume, the reaction rate will become ' x ' times of the original reaction rate. The value of x is :

Options

  1. A3
  2. B1 9
  3. C9
  4. D1 3

Correct answer

C. 9

Step-by-step solution

Since, the reaction is elementary Rate =k[A]^1[B]^1 When V is reduced to 1 3 ~V , concentration will be tripled. Hence, rate =9 ( rate )_ initial x=9
