rate of reaction

Cards (5)

  • a reaction can only happen if
    particles collide
    collisions must have a certain minimum energy value- activation energy
  • increase concentration
    more particles in same volume increasing number of successful collisions and the rate
  • increase surface area
    spreads the particles out so increasing the number of success full collisions and rate
  • increase temp
    gives particles more kinetic energy
    particles moved and collide more
    collide harder so more successful collisions
  • add a catalyst
    speed up a reaction by providing lower activation energy pathway for the reaction
    catalysts can be used over and over again and they a specific to a reaction
