Calculations Involving Kc
What is Kc equal to?
concentration of the products divided by the concentration of the reactants
concentrations are raised to the power of the moles of that substance
Describe the 3 main features of dynamic equilibrium
rate of forward reaction is equal to the rate of backward reaction
concentration of reactants is equal to concentration of products
takes place in closed system
What is the difference between homogeneous and hetrogeneous reactions?
homogeneous reactions are reactions in which the reactants and products are
in the same phase
whereas hetrogeneous reactions are reactions in which some of the reactants
and/or products are in different phases to each other
What is the difference when calculating Kc for a hetrogeneous reaction?
any terms representing a solid or liquid are not included in the calculation
