reversible reaction and equilibrium

• describe reversible reaction

  products can react to produce original reactants
• describe equilibrium

  forward and backward reactions occur at same rate with constant concentration of reactants and products
• describe factors affecting position of equilibrium

  • temperature
  • concentration
  • pressure
• describe affect of temperature on position of equilibrium

  increase - endothermic

  decrease - exothermic
• describe affect of concentration on position of equilibrium

  opposite side
• describe affect of pressure on position of equilibrium

  increase - less molecules

  decrease - more molecules
