Rate of Reaction
A catalyst increases the rate of reaction but remains unchanged at the end of a reaction. Only a small amount of the catalyst is needed. A catalyst is specific to a particular reaction
- Large lumps have a smaller surface area.
- Small lumps have a larger surface area
- Powders have a much greater surface area
- If smaller lumps of a solid are used the surface area increases so the particles have more effective collisions per second. This means the reaction is faster.
An explosion is a very fast chemical reaction that makes and releases large volumes…
