The heat capacity of chloroform (trichloromethane, CHCl3) in the range 240 K to 330 K is given by Cp,m/(J K–1mol–1) = 91.47 + 7.5 ´ 10–2 (T/K). In a particular experiment, 1.00 mol CHCl3 is heated from 273 K to 300 K. Calculate the change in molar entropy of the sample.
The molar heat capacity of trichloromethane (chloroform, CHCl3) in the range 240 K to 330 K is given by Cp,m/(J K−1 mol−1) = 91.47 + 7.5 × 10−2(T/K). Calculate the change in molar entropy when CHCl3 is heated from 273 K to 300 K.
