  • What factor does not affect the reaction rate?
    The color of reactants does not affect reaction rate.
  • What factor does not affect the rate of reaction?
    The color of reactants does not affect the rate of reaction.
  • Which of these factors will cause a solid solute to dissolve faster?
    Increasing temperature, stirring, or increasing surface area will cause a solid solute to dissolve faster.
  • What two factors speed up rates of chemical reaction and weathering in rocks and soils?
    Higher temperature and increased surface area speed up rates of chemical reaction and weathering.
  • Which changes will increase the rate of reaction during combustion?
    Increasing temperature, reactant concentration, surface area, or adding a catalyst will increase combustion rate.
  • Methane and oxygen react to form carbon dioxide and water. The reaction speed can be increased by:
    Increasing temperature, reactant concentration, surface area, or adding a catalyst.
  • The data showed that for higher temperatures, the reaction rate:
    The reaction rate increases at higher temperatures.
  • All of the following are factors that affect the rate of a reaction except _____
    Color of reactants does not affect the rate of a reaction.
  • Classify the actions based on how they could affect a reaction rate.
    Actions that increase reaction rate: increase temperature, concentration, surface area, or add a catalyst. Actions that decrease rate: decrease temperature, concentration, surface area, or remove a catalyst.
