For a gaseous reaction, following data is given: A ⟶ B , k 1 = 10 15 e - 2000 / T C ⟶ D , k 2 = 10 14 e - 1000 / T The temperature at which k 1 = k 2 is :

Options

  1. A1000 K
  2. B2000 K
  3. C868.82 K
  4. D434.2 K

Correct answer

D. 434.2 K

Step-by-step solution

When k 1 = k 2 , 10 15 e - 2000 / T = 10 14 e - 1000 / T 10 = e 1000 / T 2.303 l o g 10 = 1000 T T = 434.2 K
