5. For each of the following acid-base equilibria:I.Draw the structures of the conjugate acid and conjugate base that would be the products of the reaction aswritten.II. Use your knowledge of pKa values from lecture to estimate the value of the equilibrium constant, Keq, for thereaction. Be sure to show your work.III. Bearing in mind your answer for II, predict whether reactants, products, or neither would be favored by thereaction system at equilibrium. (Circle the side that is favored, or simply write "neither.") No explanation isnecessary.(a)CH3CH2O+ H3CCH3(b)H3CC=C-H CH3NH(c)CI+PhOH(d)HCN + NH3

1. Compare your pKa, Ka and molar mass from your experiment to the expected values for KHP. How well do they compare? What might account for the differences? 2. Based on your results in Part 1, is the method used reliable in determining pKa, Ka and molar mass of a weak acid? Explain. 3. Discuss your thinking on how you determined the identity of your unknown. Were there two (or more) acids that were difficult for you to distinguish between? If so, how did you makeyour final decision?
