  • Speed of reaction
    • Speed of reaction = amount of reactant used up / time taken
    • Speed of reaction = amount of product obtained / time taken
    • rate = 1 / time = 1 / second = 1 / s = s^-1
    • Speed of reaction = volume of gas produced / time taken
    • Acivation Energy (Ea) is defined as the minimum value of kinetic energy which particles must have before they are ale to react
    • Greater kinetic energy as compared activation energy known as effective collisions
    • Factors which affect the rate of reaction: increase rate of reaction
      • Increase temperature at the experiment
      • increase concentration of the aqueous reactant
      • Increase pressure of gaseous reactant
      • decrease particle size of solid reactant
      • the use of a catalyst
