Equilibrium expressions and the equilibrium constant, Kc
defenition: Constant value calculated from the equilibrium expression that are specific for every reaction in terms of concentration of each individual substance involved in the reaction.
formula
mA + nB ⇌ pC + qD
(where m, n, p and q are the number of moles in the stoichiometric equation)
Kc = [C]^p [D]^q / [A]^ m [B]^n
Units of Kc:
Unit of Kc = (mol dm-3)𝚺 products - 𝚺 reactants
Where : 𝚺products = total stoichiometric coefficients of all products in the reaction.
𝚺reactants = total stoichiometric coefficients of all reactants in the
Equilibria in gas reactions: the equilibrium constant, Kp
defenition: Constant value calculated from the equilibrium expression of reaction that are specific for every reaction in terms of partial pressure of each individual gases involved in the reaction
formula:
mA(g) + nB(g) ⇆ pC(g) + qD(g)
m, n, p, q = stoichiometric coefficient of reactans and products in the equation
Kp = P^p C Q^q D / P^m A Q^n B
units of Kp:
Unit of Kp= (atm / Pa) 𝚺 products - 𝚺 reactants
where:
Σreactant = total stoichiometric coefficients all gaseous reactants in the reaction
Σproducts = total stoichiometric coefficients all gaseous products in the reaction
