Why is catalyst added while preparing oxygen from decomposition of
Why is catalyst added while preparing oxygen from decomposition of \( K C l O_{3} ? \)
- A. to increase the rate of reaction
- B. \( K C l O_{3} \) decomposes at lower temperature
- C. catalyst undergoes no change chemically or in mass
- D. all of the above
Step-by-step solution
A catalyst increases the rate of decomposition (A), allows the reaction to proceed at a lower temperature (B), and remains chemically unchanged and in mass after the reaction (C). Thus, all given statements are correct.
