Fifty grams of solid I₂ is placed in a 1 liter evacuated cell and allowed to come to equilibrium with its vapor at 120°C. What is the partial pressure of I₂ vapor in the cell when it reaches equilibrium?

Question

Quizplus · Accepted Answer

The correct answer is A because the partial pressure of I2 vapor in the cell when it reaches equilibrium is 18 Torr. This is because the vapor pressure of I2 at 120°C is 18 Torr, and the partial pressure of a gas in a mixture is equal to the vapor pressure of the gas at that temperature.
