  • If the concentration of a reactant increases, the reaction rate increases. There are more molecules in the same volume so there is a greater chance of the molecules colliding and therefore a greater chance that there will be more collisions with energy greater than the activation energy in a certain length of time
  • For a gaseous reaction, increasing the pressure is the same as increasing the concentration
  • For a solid, increasing the surface are has the same effect
  • Always mention collision theory!^
  • If the temperature of a reaction increases, the reaction rate increases. At higher temperatures the molecules have more kinetic energy and are moving faster. More molecules have an energy that is greater than the activation energy and more collisions take place in a certain length of
