Question 6 ( 10 pts) The molar heat capacity of anhydrous potassium hexacyanoferrate (II) depends on the T as follows: T/K Cp.m/(JK ' mol"' ) 10 2.09 20 14.43 30 36.44 40 62.55 50 87.03 60 111.0 70 131.4 80 149.4 90 165.3 100 179.6 110 192.8 150 237.6 160 247.3 170 256.5 180 265.1 190 273.0 200 280.3 (1) Use Debye T'-law to determine the change in entropy between OK and 10 K. (2 pts) (2) Determine the third law entropy of potassium hexacyanoferrate (II) at 200 K by plotting the data, fitting it to a polynomial function, and then integrating the function you found over the range of OK to 200K.
