Complete Question:
Consider the following mechanism for the oxidation of carbon monoxide: 2 NO2(g) → N03(g) + NO(g) NO3(g) + CO(g) → NO2(g) + CO2(g) (2) Write the chemical equation of the overall reaction. Are there any intermediates in this mechanism? If there are intermediates, write down their chemical formulas. Put a comma between each chemical formula, if there's more than one.
Answer:
Overall reaction: NO₂(g) + CO(g) → NO(g) + CO₂(g)
Yes, there's one intermediary.
NO₃.
Explanation:
The overall reaction is the reaction that is formed by the addition of the reaction steps. In this case, there are two steps. If there are substances presented on both sides of the equation, they may be canceled. They are named as intermediaries.
(1) 2NO₂(g) → NO₃(g) + NO(g)
(2) NO₃(g) + CO (g) → NO₂(g) + CO₂(g)
-------------------------------------------------------
2NO₂(g) + CO(g) → NO(g) + NO₂(g) + CO₂(g)
NO₂(g) + CO(g) → NO(g) + CO₂(g)
The bolded elements represent the ones that are canceled (NO₃) and simplified (NO₂). So, there is one intermediary, it is presented only in the steps reactions: NO₃.
