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 A mixture of carbon dioxide (CO₂) gas and nitrogen (N₂) gas at 2 atm and -5° C. A 0.35 M solution of sucrose in water, and a beaker of pure water, both at 37.°C. A solution made of potassium chloride (KCl) in water, at 64°C. Change An additional 2.0 L of pure N₂ gas is added to the mixture, with the pressure kept constant at 2 atm. 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. 50. mL of pure water is added to the solution.

a) With reference to the molecules below, explain the factors which govern the watersolubility and melting points and explain the differences in the values observedbelow.b) You are a chemical engineer working in a pharmaceutical manufacturing plant.You’ve been tasked with scaling up the synthesis of a potential drug candidate.From previous studies, you know the following information about reaction takingplace:ΔHoreaction = -112.2kJΔS = -15.26JK-1mol-1ΔG = -18.81kJ Discuss the meaning of each term/value and what this tells you aboutthe nature of the reaction. Given the above information, briefly state the impact of low/hightemperatures on the above reaction.

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.

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.
