... What determines whether a reaction will actually occur spontaneously or not? In chemistry, a "spontaneous" reaction is a reaction that will occur on its own - it may be fast or it may be slow. Here are some examples of spontaneous chemical reactions: Na(s) + ½Cl2(g) → NaCl(s) + 411.2 kJ H2(g) + ½O2( ...
