For the reaction, 2 ~N ₂ O ₅ 4 NO ₂+ O ₂ , the rate equation can be expressed in two ways - d [ N ₂ O ₅ ] dt = k [ N ₂ O ₅ ] n nd + d [ NO ₂ ] dt = k ^ [ N ₂ O ₅ ] k and k ^ are related as:

Options

  1. Ak = k ^
  2. B2 k = k ^
  3. Ck =2 k ^
  4. Dk =4 k ^

Correct answer

B. 2 k = k ^

Step-by-step solution

Rate of disappearance of reactant = Rate of appearance of products aligned &- 1 2 d [ N ₂ O ₅ ] dt = 1 4 d [ NO ₂ ] dt & 1 2 k [ ~N ₂ O ₅ ]= 1 4 k^ [ N ₂ O ₅ ] & k 2 = k^ 4 & k^ =2 k aligned
