Questions
Base your answers to questions 73 through 74 on the information below.
The catalytic converter in an automobile changes harmful gases produced during fuel combustion to less harmful exhaust gases. In the catalytic converter, nitrogen dioxide reacts with carbon monoxide to produce nitrogen and carbon dioxide. In addition, some carbon monoxide reacts with oxygen, producing carbon dioxide in the converter. These reactions are represented by the balanced equations below. Reaction 1: 2NO2(g) + 4CO(g) ==>N2(g) + 4CO2(g) + 1198.4 kJReaction 2: 2CO(g) + O2(g) ==>2CO2(g) + 566.0 kJ73 The potential energy diagram in your answer booklet represents reaction 1 without a catalyst. On the same diagram, draw a dashed line to indicate how potential energy changes when the reaction is catalyzed in the converter. [1]
