Gce Model Questions Vol1 2023 Chemistry Question 10
Practice objective / multiple choice question 10 from the 2023 Gce Model Questions Vol1 Chemistry examination.
A mixture containing 0.200 mol of chloroform (CHCl₃) and 0.300 mol of carbon tetrachloride (CCl₄) is placed in a sealed 5.00 L container at 25 °C. The vapour pressures of the pure liquids at 25 °C are \(P^{\circ}_{\text{CHCl}_{3}}=0.190\,\text{atm}\) and \(P^{\circ}_{\text{CCl}_{4}}=0.100\,\text{atm}\). Assuming the liquids form an ideal solution, calculate the total pressure above the solution using Raoult's law. Then, if the temperature is raised to 35 °C where the vapour pressures become \(P^{\circ}_{\text{CHCl}_{3}}=0.260\,\text{atm}\) and \(P^{\circ}_{\text{CCl}_{4}}=0.140\,\text{atm}\), determine the new total pressure.
