Question:

Standard practice in chemical laboratories is to distill highboiling-point substances under reduced pressure. Trichloroacetic acid has a standard enthalpy of vaporization of 57.8 kJ · mol–1 and a standard entropy of vaporization of 124 J · K–1 · mol–1. Use this information to determine the pressure that is needed to distill trichloroacetic acid at 100.°C.
