1.5 Kinetics

• Collision theory states for a reaction to occur particles must collide with sufficient energy and in the correct orientation
• effect of temp on ror

  increases kinetic energy -> particles move faster -> more frequent successful collisions

  
  

  graph: moves right and down
• effect of conc and pressure on ror

  particles are closer together -- more molecules available to collide in a given volume -> more frequent successful collisions

  graph: moves up and right
• effect of catalyst on ror

  provides an alternative path that requires a lower Ea for a reaction to take place

  graph: curve stays the same, position of Ea shifts left
