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) (r₂=2 r₁=k[4 A]^n ) ...(ii) Divide Eq. (ii) by (i). ( aligned & & (2)^1 & =(4)^n=(2)^ 2 n & & 2 n & =1 & & n & = 1 2 =0.5 aligned ) Hence, the correct option is (c).
