Consider a system where 2.40 mol of CH3CN(g) are converted into CH3CN(I) at 1.00 atm and 82.0 °C. The normal boiling point of CH3CN is 82.0 °C, and AvapH = 29.75 kJ mol¬1. Assume the volume of CH3CN(I) is much less than the volume of CH3CN(g). What is the enthalpy change for the process described above? Enter your answer in kilojoules accurate to three significant figures. Do not use scientific/exponential notation. AH= Number kJ. What is the work done during the process described above?
