Rate of reaction
Factors that effect rate of reaction
Temperature
When the temperature increases the particles gain more energy and collide more frequently and more successfully. This means that the rate of reaction increases.
Surface area
a surface area to volume ratio is important if the SA is more than the volume there is more area for the particles to collide and more frequent and successful collisions which increases the rate of reaction
concentration/pressure
more particles in the same volume means the frequency of collisions increases which means the rate of the reaction
catalysts
speeds up the reaction
The total mass reactants converted to products in a given time
This can be measured in different ways
The amount of reactants used / time taken
Centimetres / seconds
Decimetres per second
Moles per seconds
The amount of product formed / time taken
Mass / seconds
The rate would start really fast and slow down closer to the ends as there are less reactants
They form curved graphs
mass produced
reactants used
To find the rate of reaction at a specific time use a tangent
Finding the rate of reaction from volume of gass produced:
Finding the rate of reaction from masses produced
Finding he rate of reaction from reactants broken
