Unformatted text preview: Unless otherwise specified, the numbers refer to the Exercises (not Problems) in Physical Chemistry , 9 th Edition , by Peter Atkins and Julio De Paula. Numerical answers for the (a) exercises these are available in the back of the textbook, and more complete answers are in the Student Solutions Manual. 20.2320.27 20.30  20.33 For 20.30 and 20.33, note that in 3 dimensions, the displacement is 〈 r 2 〉 1/2 = ( 3 〈 x 2 〉 ) 1/2 Problem 24.13 (but only calculate D and a , not the number of water molecules).  Answer to A: A) Using the diffusion coefficient, D, for I 2 in benzene, compute effective radius, a, for I 2 . Then solve for viscosity of hexane = 0.316 x 103 kg / (meter second) = 3.16 x 104 kg / (meter second) 18...
