Rates of Reaction

• Why is the rate of reaction important in the chemical industry?

  Faster production increases chemical output
• What does the rate of a chemical reaction measure?

  How fast reactants change into products
• What is one of the slowest chemical reactions?

  Rusting of iron
• What type of reaction is burning classified as?

  Fast reaction
• How do explosive reactions compare to burning?

  Explosive reactions are faster than burning
• What can be recorded to find the speed of a reaction?

  Amount of product formed or reactant used
• What does a steeper line on a reaction graph indicate?

  A faster rate of reaction
• What happens to the line on a reaction graph over time?

  It becomes less steep as reactants are used
• What characterizes the quickest reactions on a graph?

  Steep lines that flatten quickly
• How do the graphs represent different reaction speeds?

  • Graph 1: Original reaction speed
  • Graphs 2 and 3: Faster reactions with same reactants
  • Graph 4: More product and faster reaction due to added reactants
• What does a flat line on a reaction graph signify?

  The reaction has finished
• What happens when more reactants are added at the start?

  It results in a faster reaction
