10 - Equilibrium Ⅰ
● ***Equilibrium: a reaction in which there is no further change to the concentrations
of reactants & products

● ***Le Chatelier’s principle: when the conditions of a system are changed,
equilibrium moves to counter (minimise) the effect of the change
● Some reactions are readily reversible and can reach a state of dynamic equilibrium
(in a closed system), in which:
○ Rate of forward reaction = rate of backward reaction
○ Concentrations of reactants & products remain constant
● Equilibrium ≠ dynamic equilibrium: chemical equilibrium occurs when reaction comes
