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 O AS = 0 1.0 g of sodium bromide (NaBr) g and 2.0 L of pure water at 36 °C. The sodium bromide is dissolved in the water. AS > 0 not enough information 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). о AS > 0 not enough information O AS < 0 o AS = 0 A mixture of argon (Ar) gas and xenon (Xe) gas at 5 atm and 41°C An additional 2.0 L of pure Xe gas is added to the mixture, with the pressure kept constant at 5 atm. AS > 0 not enough information
