The heat capacity, Cp, of liquid carbon disulfide is a relatively constant 78J(molK). However, the heat capacity of solid carbon disulfide varies greatly with temperature. From 99K to its melting point at 161K, the heat capacity of solid carbon disulfide increases linearly from 44 J/(molK) to 57 J/(molK). The enthalpy of fusion of carbon disulfide is 4390 J/mol. The absolute entropy of liquid carbon disulfide at 298K is 151 K/(molK). Estimate the absolute entropy of carbon disulfide at 99K.
