Problem
Ammonium chloride dissolves in water spontaneously in an endothermic process. Identify the best explanation for these observations.
(1) Endothermic processes are energetically favourable.
(2) The bonds in solid NH4Cl are very weak.
(3) The entropy change of the system drives the process.
(4) The entropy change of the surroundings drives the process.
