To solve the problem, we need to calculate the entropy change for two processes involving benzene (C₆H₆) at its boiling point (80.1°C). ### Given: - Enthalpy of vaporization (ΔH_vaporization) = 30.8 kJ/mol - Boiling point (T_b) = 80.1°C ### Step 1: Convert ΔH_vaporization to Joules Since entropy is typically expressed in Joules, we need to convert the enthalpy of vaporization from kJ to J. ...
