Reaction rate laws

When we investigate the rate of reaction we are looking at the...

• amount of product formed

• speed of reaction

• concentration of reacting particles

• combining reactants with products

Reaction order defines...

• how many reactions a reactant can do

• how the rate is affected by the concentration of that reactant

• the weight of reactants of a chemical reaction

• the order in which the reactants line-up to react and form products

How do we find the overall order of a chemical reaction?

• Add all the reaction orders of each reactant

• Subtract all the reaction orders of each reactant

• Multiplyall the reaction orders of each reactant

• We need to find moles, add them all together and multiply by 100

• Zero-order

• First-order

• Second-order

• Triple-order
