Rates of Reactions

• What does a steeper line on a rate of reaction graph indicate?

  Faster rate of reaction
• How can the amount of product in a reaction be measured?

  By measuring solids, liquids, or gases
• What does a flat line on a reaction graph signify?

  The reaction has finished
• How is time typically measured in reactions?

  In seconds
• What is the formula for mean rate of reaction?

  Mean rate = Amount of product formed / Time
• What are the three common units of rate?

  cm³/s, mol/s, g/s
• How can the rate of reaction be found at a specific point on a graph?

  By drawing a tangent to the curve
• How do you calculate the rate gradient on a rate graph?

  Change in y / change in x
• How do you work out the mean rate over a period of time?

  Overall change in y / total time taken
• What is the relationship between reactant amount and product formation?

  • More reactant leads to more product
  • Product formation is directly proportional to reactant amount
• What factors affect the rate of reaction?

  • Concentration of reactants
  • Temperature
  • Surface area of solids
  • Presence of catalysts
• What is the significance of measuring rates of reaction?

  • Helps understand reaction dynamics
  • Allows optimization of reaction conditions
  • Essential for industrial applications
