2KClO\(_3\)(s) → 2KCl(s) + 3O\(_2\)(g)
The importance of the catalyst in the reaction above is that
- heating may not be required before the reaction takes place
- the reaction is controllable even at a high temperature
- the reaction produces large quantity of oxygen
-
the reaction takes place more rapidly at a lower temperature
The correct answer is: D
Explanation
A catalyst is a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditions (as at a lower temperature) than otherwise possible.
