M2 Chemistry - Coggle Diagram

- - - - no new substance created
      - change of state
      - change in the amount of energy of the particles
      - easily reversed
  - - - if collision is unsuccessful, no chemical reaction will happen
      - requirement 1: particles which collides contain sufficient amount of activation energy Ea
        
        def: the minimum amount of energy associated with particles for a reaction to occur
        
        required to break old bonds and form new ones
        
        only catalyst can lower activation energy and increase the collision frequency
      - requiremetn
    - - factors
        
        collision frequency, which is the amount of collision occurring per unit of time
        
        the energy of which particles collide, because the faster the particles collide, the faster the reaction will happen
      - def: how fast a reaction occurs
      - calculation
        
        change in mass or volume / time taken
        
        g/s or cm^3/s
