reaction profiles

• how do chemical reactions occur


  when reacting particles collide with each other with sufficient energy
• activation energy


  the minimum amount of energy that particles must have to react
• endothermic reaction


  • The energy of the products will be higher than the energy of the reactants, so the change in energy is positive

  
• exothermic reaction 


  • The energy of the products will be lower than the energy of the reactants, so the change in energy is negative
