Chemistry · Rate of a chemical reaction, factors affecting the rate of reactions: concentration, temperature, pressure and catalyst
Decomposition of is retarded by
Decomposition of \( \boldsymbol{H}_{2} \boldsymbol{O}_{2} \) is retarded by
- A. Acetanilide
- B. \( M n O_{2} \)
- C. zinc
- D. finely divided metal
Step-by-step solution
Acetanilide acts as a stabilizer or negative catalyst, retarding the decomposition of hydrogen peroxide. In contrast, MnO2, zinc, and finely divided metals act as positive catalysts, accelerating the decomposition.
