Why is the reaction of the dissolving ammonium nitrate (NH4NO3) in water spontaneous even though the dissolution is endothermic?
a vapor pressure of water decreases upon addition of the solute
b osmotic properties predict this behavior
c because of the decrease in enthalpy upon addition of the solute
d because of the increase in enthalpy upon dissolution of this strong electrolyte
e because of the increase in disorder upon dissolution of this strong electrolyte
