Nitric oxides, NO and NO_2, contribute to air pollution, acid rain, and the depletion of the ozone layer. After NO forms in the combustion chamber of an automobile engine, it reacts further with oxygen to form NO_2. The reaction is given by 2NO (g)} + O2(g)rightarrow 2NO2(g) The following table gives some entropy values: Substance Delta S^ (J/mol\ K) NO_2 240.0 O_2 205.2 NO 210.8 Part A Calculate Delta S rxn^\circ for the reaction 2NO (g) + O_2(g)} \rightarrow 2NO_2(g)
