  • Rate of reaction
    • How it is affected? How it is increased?
      • Temperature
        • Increase in temperature
      • Concentration/pressure
        • Increase
      • Catalyst
        • Catalyst added
      • Surface area
        • Solid cut into smaller pieces
    • Measuring
      • Rate = amount of reactant / Time
      • Percipitation
        • When its no longer transparent
        • Cross under liquid
      • Change in mass
        • Gas was released
        • Quicker mass drop, quicker reaction
      • Volume of Gas given off
        • Through gas syringe
    • Experiments
      • Hydrochloric acid and marble chips
        • Measured through gas volume
        • Changing surface area
        • Finer pieces act faster
      • Magnesium and Hydrochloric acid
        • Increasing concentration
        • Measured with mass balance
        • Higher acid concentration acts faster
      • Sodium Thiosulfate and Hydrochloric acid
        • Measured through the transparency
        • Increasing surface area
        • Higher temperature acts faster
      • Breaking down of Hydrogen Peroxide
        • Catalyst added
        • Better catalysts give a better reaction
        • Measured through gas syringe
