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
Correct answer is D
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.
