Worked Solution & Example Answer:Oxides of nitrogen are produced by the combustion of coal - HSC - SSCE Chemistry - Question 12 - 2002 - Paper 1
Step 1
Which of the following is the most effective method for removing oxides of nitrogen produced by the combustion of coal?
Answer
To determine the most effective method for reducing oxides of nitrogen emissions, we analyze the data presented in the graph. The graph indicates the percentage of oxides of nitrogen remaining in emissions for each method.
Based on the graph, the method with the lowest remaining percentage of oxides of nitrogen is 'Selective catalytic scrubbers.' Therefore, among the provided options, the most effective method is:
(D) Selective catalytic scrubbers.
