Endo and Exothermic reactions

• Endothermic Reaction Graph

  A) energy

  B) progress of reaction

  C) reactants

  D) products

  E) energy is absorbed

  F) activation energy

  
• Exothermic Reaction Graph

  A) energy

  B) progress of reaction

  C) energy is released

  
• The activation energy is the minimum amount of energy for bonds to break and a reaction to start
• If energy input is less than the activation energy, the reaction will not take place and nothing will happen
