Ammonium nitrate (NH4NO3) dissolves readily in water even though the dissolution is endothermic by 26.4 kJ/mol. The solution process is spontaneous because __________.




  1. of the increase in disorder upon dissolution of this strong electrolyte
  2. the vapor pressure of the water decreases upon addition of the solute
  3. of the decrease in enthalpy upon addition of the solute
  4. osmotic properties predict this behavior
  5. of the increase in enthalpy upon dissolution of this strong electrolyte 



Answer: of the increase in disorder upon dissolution of this strong electrolyte.
