The Effect of Temperature on Rate of Reaction
The effect of temperature on a reaction rate
In this experiment I shall be investigating how temperature affects the rate of reaction
Rates of reaction
The Factors that affect the rate of reaction are temperature, surface area, concentration, catalysts, light and pressure
Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our experiment - When the surface area increases the rate of reaction increases as there is more surface area for the particles to work on, thus, there are more collisions per second - Example : It is easier to light a fire with small pieces of stick than using large blocks of wood
Concentration - Concentration is the amount of molecules of a substance in a given volume - Concentration affects solids, gases and liquid so this will affect our experiment - When the concentration increases the rate of reaction increases as there are more molecules present, therefore there are more collisions between molecules (Collision theory) - Example : zinc reacts fairly slowly with dilute hydrochloric acid but when the acid is concentrated, the rate of reaction increases.
Catalysts - A catalyst is a substance which speeds up the rate of reaction without itself going undergoing any permanent chemical change – this means only small amounts of catalysts are needed to speed up
