|
One mole of gas |
Occupies 24dm3 (24,000cm3) at room temperature. |
|
|
Reversible reaction |
Where the products of a reaction can react themselves to produce the original reactants. |
|
|
Dynamic equilibrium |
Reactions take place in both directions but the overall effect is nil as they cancel each other out. The rate of the forward reaction is equal to the rate of the backwards reaction. |
|
|
Exothermic reaction |
Favours cooler temperatures |
|
|
Endothermic reaction |
Favours warmer temperatures. |
|
|
Higher pressure |
Favours the reaction with the lowest volume. |
|
|
Lower pressure |
Favours the reaction with the highest volume. |
|
|
Catalysts |
Speed up the forward and backward reactions the same amount. The reaction reaches equilibrium quicker |
