EQUILIBRIUM
At Equilibrium:
• the amounts of reactants /
products do not change with time.
products do not change with time.
• rate of forward & back reaction are equal
Kc = [product C]c
[reactant A]a [reactant B]b
[reactant A]a [reactant B]b
• a, b, c are from the
balanced equation
• Kc is the equilibrium
constant which tells
us the extent of reaction at completion.
