In the chemical reaction A B , what is the order of the reaction? Given that, the rate of reaction doubles if the concentration of A is increased four times.

Options

  1. A2
  2. B1.5
  3. C0.5
  4. D1

Correct answer

C. 0.5

Step-by-step solution

We know, r₁=k[A]^ n ....(i) If conc. of A is increased four times rate of reaction on doubles. 2 r₁=k[4 A]^ n ....(ii) Divide Eq. (ii) by (i). 2 r_i r₁ = k(4 A)^n k(A)^n 2=(4)^ n 2 n =(2)^ 2 n n=0.5
