O ENTROPY AND FREE ENERGY Predicting qualitatively how entropy changes with mixing and ... 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 O AS < 0 AS = 0 20. L of pure krypton (Kr) gas and 20.0 L of pure hydrogen (H2) gas, both at 4 atm and -19°C. The gases are mixed, with the pressure kept constant at 4 atm. O AS > 0 not enough information Ο Ο Ο Ο Ο Ο O AS < 0 AS = 0 A liter of seawater at 15°C. 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). AS > 0 not enough information O ASSO Oo oo O AS = 0 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. A 0.35 M solution of sucrose in water, and a beaker of pure water, both at 37.°C. OAS > 0 o not enough information х 5 ?
