What is the order of the following reaction ? 2 H ₂ O ₂ (l) 2 H ₂ O (l) + O ₂ (g) , if rate = k [ H ₂ O ₂]

Options

  1. A0
  2. B1
  3. C2
  4. D3

Correct answer

B. 1

Step-by-step solution

The rate law for the given reaction is provided as rate = k [ H ₂ O ₂] . The order of a reaction is defined as the sum of the exponents of the concentration terms in the rate law expression. In this rate law, the exponent of the concentration of H ₂ O ₂ is 1 . Therefore, the order of the reaction is 1 . Answer: 1
