Which of the following statement is NOT true for a reaction having rate law r = k [ H ₂ ] [ I ₂ ] ?

Options

  1. AThe reaction is first order in H ₂
  2. BOverall order of reaction is 1
  3. CThe reaction is first order in I ₂
  4. DOverall order of reaction is 2

Correct answer

B. Overall order of reaction is 1

Step-by-step solution

r = k [ H ₂ ] [ I ₂ ] Overall order of reaction is 2 . Order of reaction wrt H ₂ is 1 and Order of reaction wrt I₂ is 1 .
