2. When distributing phenol between water and benzene, the following data were obtained
С1 (in water), mol/l 0.0316 0.123 0.327 0.750
С2(in benzene, mol/l 0.077 0.159 0.253 0.390
Calculate the average value of the distribution coefficient K and the exponent n in the formula С1^n/C2=K. Answer: Ksr = 2.171
