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 removing oxides of nitrogen produced by coal combustion, we can analyze the graph that presents the percentage of oxides of nitrogen remaining in emissions after using various technologies.
From the graph, it is evident that 'Selective catalytic scrubbers' have the lowest percentage of oxides of nitrogen remaining in emissions compared to the other methods listed. This indicates that this technology is the most effective in reducing these harmful emissions.
Thus, the recommended answer is (D) Selective catalytic scrubbers.
