Rates Of Chemical Reactions
This is a draft cheat sheet. It is a work in progress and is not finished yet.
Reaction Rate
Change in reactants/products' concentration over time |
Factors That Increase Reaction Rate
Surface area |
Concentration |
Pressure |
Temperature |
Catalysts |
| |
Increasing Above Factors Also Increases... |
Collision frequency |
Successful collisions amount |
| |
Temperature Increase Also Increases... |
Collision energy |
|
|
Experiment Methods To Measure Reaction Rate
Mass loss |
Gas volume made |
Colour change |
Concentration changes |
pH change |
Catalysts
Provides an alternative reaction pathway with lower activation energy |
Speeds up reaction & isn't used up |
Causes more particle collisions |
| |
Heterogenous Catalysts |
Homogenous Catalysts |
Has different state to reactants & producs |
Has same state as reactants & products |
|
|
Transition State
Unstable state |
Reactants' bonds broken & products' bonds forming |
Triggered by activation energy |
Collision Theory
Particle collision affects chemical reaction rates |
| |
Collision Requirements Of Reactant Particles |
Collision with each other |
Collision with enough energy |
Collision in the right direction |
|
