For the decomposition of a compound A B at 600 ~K , the following data were obtained The order for the decomposition of A B is

Options

  1. A1.5
  2. B0
  3. C1
  4. D2

Correct answer

D. 2

Step-by-step solution

AB Product Rate = k [ AB ]^ n (Rate) )₁= k [0.20]^ n =2.75 10⁻⁸ ...(i) (Rate) ₂= k [0.40]^ n =11.0 10⁻⁸ ...(ii) Dividing Eq. (ii) by Eq. (i), array lrl & 2^ n & =4 or & 2^ n & =2² Hence, & n & =2 array
