(5) exo + endo

    Cards (6)

    • what do we call reactions which transfer energy to the surroundings
      exothermic
    • a white powder dissolves in water to form a solution. the temperature falls by 2oC. State and explain the type of reaction that has taken place

      endothermic - the temp falls because energy is taken in from the surroundings
    • which reaction profile goes low to high. endothermic or exothermic
      endothermic
    • if you calculate the overall change in bond energy for an exothermic reaction would you expect it to be + or -
      negative
    • what property of metals make them suitable for use as electrodes
      they conduct electricity
    • what is activation energy
      the minimum energy required to start a reaction
