Predicting qualitatively how entropy changes with mixing and separation For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System Change AS AS < 0 A mixture of oxygen (O2) gas and An additional 2.0 L of He pure AS = 0 gas helium (He) gas at 5 atm and 25°C. is added to the mixture, with the pressure kept constant at 5 atm. AS > 0 1.0 g of ammonium chloride (NH4Cl) and 2.0 L of pure water at 36 °C. not enough information AS < 0 AS = 0 The ammonium chloride is dissolved in the water. AS > O not enough information AS < 0 A solution made of ammonium AS = 0 chloride (NH4Cl) in water, at 50. mL of pure water is added to the solution. AS > O 36°C. not enough information ? 18 Ar 日。

System A liter of seawater at 15°C. A 0.35 M solution of sucrose in water, and a beaker of pure water, both at 37. °C. 20. L of pure oxygen (0₂) gas and 20.0 L of pure carbon dioxide (CO₂) gas, both at 5 atm and 22°C. Change The seawater is passed through a reverse-osmosis filter, which separates it into 750. mL of pure water and 250. mL of brine (very salty water). The solution is put into a semipermeable bag immersed in the water, and 50. mL of pure water flows through the bag into the sucrose solution. The gases are mixed, with the pressure kept constant at 5 atm. X AS AS 0 not enough…

12:27 Cl₂ is a stable diatomic molecule. It can be decomposed to form two Cl atoms as shown below. Cl₂(g) → 2 Cl(g) Question 12 of 15 A) AS is (-) Predict the change in entropy (AS) of this reaction.

Beginning from the Clausius inequality, derive for us several (two or more) units of entropy

the pull downs are either, increase, decrease, or remain the same

Try Again Your answer is incorrect. For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System 1.0 g of potassium chloride (KC1) and 2.0 L of pure water at 14 °C. A mixture of argon (Ar) gas and nitrogen (N₂) gas at 1 atm and - 18°C. A solution made of potassium chloride (KCl) in water, at 14°C. Change The potassium chloride is dissolved in the water. An additional 2.0 L of pure N₂ gas is added to the mixture, with the pressure kept constant at 1 atm. 50. mL of pure water is added to the solution.
