S 16.95 In the vapor phase, acetic acid molecules associate to
a certain extent to form dimers:
2CH;COOH(g) – (CH,COOH),(g)
At 51°C, the pressure of a certain acetic acid vapor
system is 0.0342 atm in a 360-mL flask. The vapor is
condensed and neutralized with 13.8 mL of 0.0568 M
NaOH. (a) Calculate the degree of dissociation (a) of
the dimer under these conditions:
(CH-COОH)2 2CH,СООН
(Hint: See Problem 15.65 for general procedure.)
(b) Calculate the equilibrium constant Kp for the
reaction in (a).
