|
Rate of reaction |
= amount of reactant used or product formed / time |
|
|
Concentration |
=amount (moles) / volume (dm^3) { measured in moles per dm^3} |
|
|
Catalyst |
A substance that increases the rate of a chemical reaction without being used up in the process |
|
|
Reversible reaction |
Products can react to produce the reactants |
|
|
Closed system |
No reactants or products can be added or removed |
|
|
Equilibrium |
When the rate of the forward reaction is equal to the rate of the backward reaction in a closed system |
|
|
Le chatelier's principle |
States that if a system in equlibrium is subjected to a change in conditions, then the system shifts to restist the change |
|
|
Collision theory |
For particles to react, they have to collide with sufficient energy (activation energy) |
