Transcript of Reaction rate How quickly or slowly reactants are turned into products is called the reaction rate.

  • Reaction rateHow quickly or slowly reactants are turned into products is called the reaction rate

  • TemperatureIncreasing temperature will INCREASEthe rate of a chemical reaction.

    Explanation:Increasing temperature increases the molecular movement of the reactants.Therefore, reactants collide more often and produce products at a faster rate.

  • Surface areaIncreasing the surface area of the reactants will INCREASE the rate of a chemical reaction.

    Explanation:Powders will react faster than solid blocks because there is more surface area for reactants to collide.

  • ConcentrationIncreasing the concentration of the reactants will INCREASE the amount of product formed in a chemical reaction.

    Explanation:Increasing concentration of reactants means more reactants to produce more products

  • CatalystsAdding a catalyst to a chemical reaction will INCREASE the rate of a chemical reaction.

    Explanation:Catalysts speed up chemical reaction but are not used in the reaction.

    Example = enzymes

  • EnzymesEnzymes are catalysts that are found in living organisms.

    These speed up chemical reactions without being used up in the reaction.

    Example: digestive enzymes
