🤓 Based on our data, we think this question is relevant for Professor Esfandiari's class at SJSU.
Step 1. Determine ΔSsys:
T = °C + 273.15 = 78 + 273.15 = 351.15 K
The enthalpy of vaporization of ethanol is 38.7 kJ/mol at its boiling point (78°C). Determine ΔSsys, ΔSsurr, and ΔSuniv when 1.00 mole of ethanol is vaporized at 78°C and 1.00 atm.
