define Kc in terms of products and reactants
Kc = [products]/ [reactants]
what does the value of Kc tell us?
indicates the relative proportions of reactants and products in the equilibrium
if the Kc value is 1, what does it suggest about the position of equilibrium?
halfway between reactants and products
if the Kc value is >1, what does it suggest about the position of equilibrium?
position of equilibrium is towards the products
if the Kc value is <1, what does it suggest about the position of equilibrium?
position of equilibrium is towards the reactant
