Using the thermodynamic data provided below, calculate the standard change in entropy when one mole of sodium sulfate is dissolved in water?
| S° (J/K·mol) |
Na2SO4(s) | 149.49 |
Na+(aq) | 60.25 |
SO42–(aq) | 17.15 |
Will the solubility of sodium nitrate increase or decrease if the temperature of the system is increased?
