Equilibrium

• Equilibrium is the rate of forwards reaction is equal to the rate of backwards reactions
• What is a closed system?

  no products or reactants enter or leave
• What are the factors that effect equilibrium?

  • temperature
  • pressure
  • concentration
• What is Le Chandeliers principle?

  If a system is at equilibrium and a change is made to any of the conditions the the system responds to counteract the change
• Catalyst do not alter the position of equilibrium
• What do catalysts do to a reaction?

  they increase the rate of forwards and backwards reactions equally.
