• What is the rate of a chemical reaction a measure of?

  How fast the reaction occurs
• What does the reaction rate depend on?

  The reaction that is taking place
• What are the variables that can affect the rate of a reaction?

  • Concentration
  • Temperature
  • Particle Size
• What happens to the reaction rate when concentration is increased?

  It speeds up the reaction
• What happens to the reaction rate when concentration is decreased?

  It slows down the reaction
• What effect does increasing temperature have on the reaction rate?

  It speeds up the reaction
• What effect does decreasing temperature have on the reaction rate?

  It slows down the reaction
• What happens to the reaction rate when particle size is increased?

  It slows down the reaction
• What happens to the reaction rate when particle size is decreased?

  It speeds up the reaction
• How does increasing concentration affect the reaction rate compared to decreasing concentration?

  Increasing concentration speeds up the reaction, while decreasing it slows down the reaction
• How do temperature changes affect the reaction rate in comparison to changes in particle size?

  Increasing temperature speeds up the reaction, while increasing particle size slows it down
