Catalytic converters are employed to eliminate oxides of nitrogen from exhaust gases. One of the reactions taking place in a catalytic converter is shown by the equation. $2\mathrm{NO} + 2\mathrm{CO} \rightarrow \mathrm{N_2} + 2\mathrm{CO_2}$. What is one disadvantage of using a catalytic converter to remove oxides of nitrogen?
- ACO is an essential reactant in photosynthesis.
- B$\mathrm{CO_2}$ is a greenhouse gas.
- C$\mathrm{N_2}$ is acidic.
- D$\mathrm{N_2}$ is toxic.
