Options

  1. AZero
  2. BFirst
  3. CSecond
  4. DThird

Correct answer

B. First

Step-by-step solution

The decomposition of hydrogen peroxide is a well-known example of a first-order reaction. The rate law for this reaction is given by: Rate = k[ H ₂ O ₂] Since the power of the concentration term in the rate law is 1 , the order of the reaction is first. Answer: First
