Catalytic Converter A.P.P Assessment
Catalytic converters are used in cars to reduce pollution and toxic gases, such as carbon monoxide. Here are the reactions that happen inside a catalytic converter: 2NOx(g) → xO2(g) + N2(g) – this is the reduction of nitrogen oxides. 2CO(g) + O2(g) → 2CO2(g) – this is the changing of carbon monoxide to carbon dioxide. There are different views on catalytic converters. The two main views are the environmental view, and the economic view. The environmental view, not surprisingly, includes looking after the environment. They are generally in favour of catalytic converters, as they reduce pollution and poisonous gases, although they do still produce carbon dioxide. The other economic view doesn’t care about the environment. All they care about is the high performance of cars and vehicles, and how cheaply they can produce. As catalytic converters make the cost of producing cars go up, they are not in favour of catalytic converters. They help catalytic converters companies because they help them make money (obviously) particularly since it has become law that all new cars have to have a catalytic converter on them. Some people have issues with catalytic converters because they feel that using up more resources than needed is wrong. However, catalytic converters still help the environment, so that issue is a difficult one to solve. It is not as if you can have sustainable metals like you can have sustainable forests. They have also been known to produce a ‘rotten egg’ smell, which is a social issue for some people. This has been improved since then, fortunately. A lot of decisions on the catalytic converters were made with economics in mind, such as the pricing and laws of them. They have to try and make catalytic converters cheaply, but they still have to work well. They did manage to do this, but they used platinum, a very expensive metal. They also used economics with laws – making it a law that all new cars had to have a...
