Question

The dissolution of ammonium nitrate, NH4NO3, in water to form an aqueous solution is spontaneous at 298 K, even though it is endothermic. Which of the following statements is correct? Select one: This process defies laws of thermodynamics. This process is enthalpy-driven. This process is expected to be spontaneous only at very low temperatures. This process is expected to become nonspontaneous at very high temperatures. This process is entropy-driven.
