Question

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 O AS = 0 A mixture of nitrogen (N) gas and carbon dioxide (CO) gas at 1 atm and 46°C. An additional 2.0 L of pure CO2 gas is added to the mixture, with the pressure kept constant at 1 atm. O AS > 0 O not enough information O AS < 0 O AS = 0 A solution made of potassium bromide (KBr) in water, at 84°C. 50. mL of pure water is added to the solution. O AS > 0 not enough information O AS< 0 O AS = 0 1.0 g of potassium bromide (KBr) and 2.0 L of pure water at 84 °C. The potassium bromide is dissolved in the water. O ASO not enough information Х $
