- B. 1
- C. 2
- D. 3
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
