A catalyst increases the rate of a reaction but it is not used up in the reaction. If a catalyst is present, the reacting particles can collide more successfully with less energy and so the reaction ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

The rate of a chemical reaction is a measure of how fast the reactants are being used up and how fast the products are being made. Reactions in which a gas is produced can be used to monitor the rate.
