K > 1 products favored K < 1 reactants favored 3. Excluded: solids; pure liquids; water (in aqueous solutions) because their [ ]?s do not change. 4. Convert from Kc to Kp Kp = Kc(RT)(n where (n = moles of gaseous product ? moles of gaseous reactant. 5. Typical question: Given Kc and the starting concentrations of reactants, find concentrations of products at equilibrium. Example: Kc for acetic acid = 1.8 x 10-5. What is the equilibrium concentration of [H+] in a 0.100 M solution of the acid? 6. Equilibrium constant for a reverse reaction = the value of the forward reaction.
