Text Solution

AI Generated Solution

To understand the relationship between the mole fraction of a gaseous component, its partial pressure, and the total vapor pressure, we can break it down step by step. ### Step-by-Step Solution: 1. **Understanding Partial Pressure**: - The total pressure of a gas mixture is the sum of the partial pressures of each individual gas in the mixture. - Mathematically, this can be expressed as: \[ ...

What is the relation between the activity of a gaseous component and its partial pressure ?

Vapor pressure of a solution of Volatile components and composition of vapor: Consider a solution containing 738 g of water and 253 g of ethanol (C_(2)H_(5)OH) at 323 K . At this temperature, the vapour pressure of pure ethanol is 0.292 atm and the vapor pressure of pure water is 0.122 atm . Calculate the vapour pressure of the solution and mole fraction of every component in vapour phase. Strategy: First calculate the moles and the mole fraction of each component in the liquid solution. Then apply Raoult's law to each of the two volatile components to calculate their partial pressures. The total vapour pressure is the sum of the partial vapour pressures of the components and the mole fraction of a components in a gaseous mixture equals the ratio of its partial pressure to the total pressure.

Read the passage given below and answer the following questions : Raoult's law states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution. Dalton's law of partial pressure states that the total pressure P_("total") over the solution phase in the container will be the sum of the partial pressures of the components of the solution and is given as: P_("total") = P_1 + P_2 Which of the following aqueous solutions should have the highest boiling point ?
