Question
At its normal boiling point of 80.1°C and 101.3 kPa pressure, benzene vapor condensing to liquid benzene is:
Correct Answer
Option C is the correct answer.
Detailed Explanation
At the normal boiling point and 1 atm pressure, vapor and liquid are in equilibrium. The rates of evaporation and condensation are equal, and ΔG = 0, so neither condensation nor vaporization is favored.
Hint
The notes provide this reasoning.
