Chapter 12, Problem 52P(choose chapter or problem)
The vapor pressure of ethanol \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) and l-propanol \(\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OH}\) at 35°C are 100 mmHg and 37.6 mmHg, respectively. Assume ideal behavior and calculate the partial pressures of ethanol and l-propanol at 35°C over a solution of ethanol in l-propanol, in which the mole fraction of ethanol is 0.300.

QUESTION:
The vapor pressure of ethanol \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) and l-propanol \(\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OH}\) at 35°C are 100 mmHg and 37.6 mmHg, respectively. Assume ideal behavior and calculate the partial pressures of ethanol and l-propanol at 35°C over a solution of ethanol in l-propanol, in which the mole fraction of ethanol is 0.300.
ANSWER:Step 1 of 2
The vapor pressure of the solvent over a solution is given by the product of the vapor pressure of the pure solvent and the mole fraction of the solvent in the solution is stated by Raoult's law.
