Measuring Rates of Reaction

• A graph with a steeper gradient at the beginning and reaching a horizontal gradient faster depicts a high rate of reaction.
• Gas Evolved

  
• Mass Loss

  
• Colour Change

  
• If a gas evolves, measure loss in mass per unit time by placing on a balance then putting a cotton wool on top to allow gas to pass but not to enter
• If a gas evolves, measure volume of gas produced per unit time using a gas syringe
• If a colour change , measure the time taken to turn cloudy
