At 18°G the molar conductivity of magnesium sulphate solution is as follows: Concn. (molel- 1 ) 0-2 0-1 0-08 0-04 0-02 0-01 0-002 AM (mho cm2) 86 100 104 120 135 152 187. Plot graphs of AM against the concentration and also of ΛΜ against the square root of the concentration, and from these show that the molar conductivity at infinite dilution is approx­ imately 228 mho cm2. 175. Estimate the molar conductivity at infinite dilution of potassium chloride solution from the following data: Concn. (mole l- 1 ) Λ Μ (ηύιοαη 2 ) 0-1 0-08 0-01 112 113-5 122-4 0-002 126-3.

Assuming that the boundary movement represents the velocity of migration of hydrogen ions, calculate the transport number of the hydrogen ion in this system, the total current being 0·025 amperes. I. PARTITION COEFFICIENT 184. What is meant by the partition coefficient of a solute between a pair of immiscible solvents? Is it always a constant? Suggest two situations that might cause it not to be constant. 185. When an organic acid is shaken up with chloroform and water, the concentration of acid in the chloroform layer is 4 times what it is in the water layer.

191. Distinguish between the order and moleculanty of a reaction. Can a bimolecular reaction ever be of the first order? Can a unimolecular reaction ever be of the second order? 192. Protactinium-234 chloride is extracted from uranium chloride solution and placed in a jo-particle counter. The rate of counting, which may be assumed proportional to the amount of protactinium-234 remaining, is read on a ratemeter at 15 second intervals, the results being: 54, 47, 46, 40, 35, 31, 29, 25, 25, 20, 17, 15, 15, 15, 12, 11, 10, 9, 9, 7, 6, 6, 6, 5, 5.
