Current Question (ID: 10557)

Question:

$\text{A balanced chemical equation for the reaction showing catalytic oxidation of NH}_3 \text{ by atmospheric oxygen is:}$

Options:

1. $4\text{NH}_3 + 5\text{O}_2 \xrightarrow[\text{500 K; 9 bar}]{\text{Pt / Rh gauge catalyst}} 4\text{NO} + 6\text{H}_2\text{O}$ (Correct)
2. $3\text{NH}_4 + 5\text{O}_2 \xrightarrow[\text{500 K; 9 bar}]{\text{Pt / Rh gauge catalyst}} 3\text{NO} + 6\text{H}_2\text{O}$
3. $4\text{NH}_3 + 5\text{O}_2 \xrightarrow[\text{cold}]{\text{no catalyst}} 4\text{NO} + 6\text{H}_2\text{O}$
4. $3\text{NH}_4 + 5\text{O}_2 \xrightarrow[\text{cold}]{\text{no catalyst}} 3\text{NO} + 6\text{H}_2\text{O}$

Solution:

$\text{HINT: All the atoms should be balanced on both sides.}$ $\text{Explanation:}$ $\text{Ammonia (NH}_3\text{) on catalytic oxidation by atmospheric oxygen in presence of Rh/Pt gauge at 500K under the pressure of 9 bar produces nitrous oxide.}$ $\text{The balanced chemical reaction can be written as:}$ $4\text{NH}_3 + 5\text{O}_2 \xrightarrow[\text{500 K; 9 bar}]{\text{Pt / Rh gauge catalyst}} 4\text{NO} + 6\text{H}_2\text{O}$
