|
Activation energy |
The minimum amount of energy that colliding particles must have for them to react |
Min ene |
|
|
Successful collision |
A collision between reactant particles that has enough energy for a reaction to happen |
Lots of ene |
|
|
concentration and pressure |
-Increasing in the concentration of a solution or pressure of a gas increases the rate of reaction -when the concentration of pressure is increased the reactant particles become more crowded this makes collisions more frequent |
Increase one thing increased other More crowded |
|
|
Surface area to volume ratio |
Lumps of a solid reactant get smaller surface area to volume ratio increases The larger surface area to volume ratio the faster the reaction When the ratio increases collisions are more frequent |
Lumps bigger Ratio increases |
|
|
Surface area |
The total area of all sides on the 3-D shape |
|
|
|
Temperature and catalysts |
Temperature increases more kinetic energy more collisions More energy more collisions |
Big temperature More collisions |
|
|
Catalysts |
Speed up a reaction without being used up Provide an alternative path with lower activation energy |
|
|
|
Enzyme |
A protein which catalyses all speeds up a chemical reaction |
|
|
|
Carbon neutral |
Not adding any more carbon into the atmosphere by burning it . |
