Rate of reactions - Topic 6

• Rate of reaction is the speed at which a chemical reaction takes place - measured by how fast or slow the reactants are used up.
• mean rate of reaction = mass/time
• A top-pan balance is used to measure the mass of the reactants decreasing (.e.g. cardon dioxide escaping causing a decrease)
• A gas-syringe is used to measure the rate of products forming to measure the volume of gas produced.
• What is the equation for rate of reaction?

  mean rate of reaction = mass/time
