Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide is N2(g) + O2(g) +2NO(9) The heat produced by an automobile engine is sufficient to convert some of the nitrogen and oxygen in the air to nitric oxide. The spontaneity of a reaction can be determined from the sign of, A-G • A reaction...
