In the reaction x A → y B , log ⁡ - d [ A ] d t = log ⁡ + d [ B ] d t + 0.3 Then, x : y is

Options

  1. A2 : 1
  2. B1 : 2
  3. C3 : 1
  4. D3 : 10

Correct answer

A. 2 : 1

Step-by-step solution

For the reaction x A → y B - 1 x d [ A ] d t = + 1 y d [ B ] d t - d [ A ] d t = + d [ B ] d t × x y log ⁡ - d [ A ] d t = log ⁡ d [ B ] d t + log ⁡ x y …(i) Given log ⁡ - d [ A ] d t = log ⁡ d [ B ] d t + 0.3 …(ii) Comparing (i) and (ii), we get log ⁡ x y = 0.3     ⇒ log   x y =   log   2 So x y = 2 1 .
