equilibrium

• forward reaction

  forms the products
• backwards reaction

  forms the reactants
• what is a reversible reaction?

  the product molecules can react with each other or decompose/reform to become the reactant molecules
• what happens to the equilibrium position when there is an increase in pressure?

  shifts in the direction with the least amount of molecules of gas
• what happens to the equilibrium position when there is an decrease in pressure?

  shifts in the direction with the largest number of gas molecules
• what happens to the equilibrium position when there is an increase in temperature?

  shifts to the endothermic side
• what happens to the equilibrium position when there is an decrease in temperature?

  shifts in the exothermic side
• dynamic equilibrium

  • can only happen in a closed system
  • the forward and backward reaction is happening at the same rate
  • the concentrations of the reactants and products remains the same
