rate of reaction graphs

• What is the purpose of plotting reaction rates?

  To calculate rates of reactions at specific times
• How is a tangent used in plotting reaction rates?

  It touches the curve at just one point
• How do you calculate the gradient of the tangent in reaction rates?

  By using change in y over change in x
• What does the rate of reaction formula represent?

  It represents the change in concentration over time
• What are the steps to plot reaction rates using a graph?

  1. Draw a tangent to the curve at a point.
  2. Calculate the gradient of the tangent.
  3. Use the formula: Rate of reaction = change in y / change in x.
• What do graphs showing mass, volume, or concentration against time illustrate?

  How different variables affect rate
• What does a steeper gradient on a reaction graph indicate?

  The reaction is faster
• What does it mean when a reaction graph plateaus?

  The reaction is complete
• How does the gradient of a reaction graph change as the reaction progresses?

  It starts steep and then slows down
• What are the key features of a reaction graph?

  • Shows mass, volume, or concentration vs. time
  • Steeper gradient indicates faster reaction
  • Plateau indicates completion of the reaction
  • Gradient changes from steep to shallow over time
