  • Why reaction rate is faster when particles have more kinetic energy (move faster).
    Particles collide more often/Collision more frequent
  • A factor that increases the rate of reaction beginning with the letter P.
    Pressure
  • How much catalyst will be left at the end of a reaction if 0.5g is added at the start?
    0.5g
  • The name for the chemicals that are formed in a reaction.
    Products
  • The term used to describe the speed of a reaction beginning with R.
    Rate
  • When there are more particles dissolved in a liquid (solvent) this increases.
    Concentration
  • Why rate of reaction increases when a solid is broken up.
    Surface area increase
  • A factor that increases the rate of reaction beginning with the letters S and A.
    Surface Area
  • What happens to the number of reactant particles when concentration is higher.
    Increases
  • Name of a chemical that speeds up a chemical reaction.
    Catalysts
  • What a catalyst decreases to cause an increase in the rate of reaction.
    Activation energy
  • The name for the chemicals that react in a reaction.
    Reactants
  • A factor that affects the rates of reaction beginning with the letter T.
    Temperature
  • What happens to the reactant particles when the temperature is higher.
    Particles move faster/More kinetic energy
  • What reactant particles must do for a reaction to occur.
    Collide
  • Why reaction rate is faster when pressure is higher.
    Particles closer together
