47. Solution to Chemistry Problem

10. Calculate the change in entropy when heating 1 mole of solid bromine from the melting point of –7.32 to 100°C, if the specific heat of fusion is 67.78 J/g, the latent specific heat of evaporation is 188.5 J/g, the boiling point is 59 C; CP,l = 75.71 J/(mol.K); the molar heat capacity of bromine vapor CP,g = 37.20 × 0.71.10-3T - 1.19.10-5T2 J/(mol.K).
