Rate of chemical change

Part of Chemistry (Single Science)

  • Rate of chemical change

    • Rates of reaction

      Chemical reactions vary in speed. The rate of reaction measures how much product is made in a given time. For reactions to occur, reactant particles must collide.

    • Factors that affect the rate of reaction

      Chemical reaction rates increase or decrease according to factors including temperature, pressure and light. A catalyst changes the rate of reaction but is unchanged at the end of the reaction.
