An aqueous solution, initially 1.00 × 10-2 M in iodine (I2),is shaken with an equal volume of an immiscible organicsolvent, CCI4. The iodine distributes itself between theaqueous and CCl, layers, and when equilibrium is reached at 27°C, the concentration of I, in the aqueous layer is1.30 × 10-4 M. Calculate the partition coefficient K at27°C for the reactionI(aq) 2 1(CCI,)
