Question

Why is catalyst added while preparing oxygen from decomposition of $KCl{O}_3$?

• A. to increase the rate of reaction
• B. $KCl{O}_3$ decomposes at lower temperature
• C. catalyst undergoes no change chemically or in mass
• D. all of the above

Answer 1

Answer: (D)

all of the above

Catalyst alters the rate of reaction, catalyst undergoes no change chemically and in mass. $KCl{O}_3$ decomposes at lower temperature by the addition of a catalyst.
