Storyboard Text

  • Concentration
  • Pressure
  • Temperature
  • Increasing the concentration of the solute or solvent increases the number of reacting particles, which increases the frequency of effective collisions. This causes the reaction rate to increase.
  • Surface Area
  • This factor applies only to gases. Increasing pressure decreases the volume of gaseous reactants. An increase in pressure also increases the concentration of gaseous reactants. An increase in the frequency of effective collisions occurs. As a result, increasing pressure in gases increase the reaction rate.
  • Adding a Catalyst
  • Increasing the temperature of a reaction increases the kinetic energy of reacting particles. This increases the frequency of effective collisions and increases the rate of reaction.
  • Ad/Commercial
  • Increasing the surface area of the solute exposes more area for more reactions to occur. Increasing the surface area increases the frequency of effective collisions which raises the rate of the reaction.
  • By adding a catalyst to a reaction, it lowers the activation energy and provides an alternate pathway for the reaction to occur. This increases the reaction rate. The catalyst does not get consumed in the reaction so after it's finished, it can be used again.
  • Selling the catalyst of potassium permanganate to scientists to speed up the process of the reaction of two molecules of hydrogen peroxide producing two molecules of watwer and one molecule of oxygen.
