equilibria

• key features of dynamic equilirium

  1. the rate of the forward reaction equals the rate of the reverse reaction
  2. the concentrations of reactants and products remain constant ( unless conditions change )
• Le Chatelier's principle

  if a system in equilibrium is subjected to a change, the position of equilibrium will move in the direction which opposes that change
• equilibrium constant

  Kc= $\frac{\left[products\right]}{\left[reac\tan ts\right]}$
• what affects the value of Kc

  only temperaure
• when there is the same number of moles on each side of the equilibrium

  volume cancles so moles can be used to calculate Kc.

  units cancel so Kc has no units
