Rate of Reaction
How quickly reactants are used up or products are made
1 of 14
Rate of reaction Equation
Mean Rate of reaction = amount of reactant used ÷ time
2 of 14

...
3 of 14
Ways to measure Rate of reaction 1
Volume of gas produced
4 of 14
Ways to measure Rate of reaction 2
Formation of a solid product
5 of 14
Ways to measure Rate of reaction 3
Change in mass

Calculating rates from graphs using a tangent:
...
7 of 14
Part 1
At start steep slope (high gradient) so fast reaction
8 of 14
Part 2
As slope becomes less steep (lower gradient) reaction is slowing
9 of 14
Part 3
Flat line (zero gradient) shows reaction has finished
10 of 14
Equilibrium:
...
11 of 14
Reversible Reaction
A chemical reaction where the products can turn back to the reactants
12 of 14
Dynamic Equilibrium
When the forwards and backwards and backwards reactions happen at the same rate in a closed system.
13 of 14
Le Charteliers Principle
A reaction at equilibrium will act to oppose any change made to it
