The rate of the reaction, A + B + C → P is given by, r = d [ A ] dt = K [ A ] 1 / 2 [ B ] 1 / 2 [ C ] 1 / 4 . The order of the reaction is

Options

  1. A1
  2. B1/2
  3. C2
  4. D5/4

Correct answer

D. 5/4

Step-by-step solution

For a reaction, A + B → Products, if rate = K [ A ] m [ B ] n , then order of reaction = m + n. r = d [ A ] dt = K [ A ] 1 / 2 [ B ] 1 / 2 [ C ] 1 / 4 Here order = 1 2 + 1 2 + 1 4 = 5 4
