For the reaction, \(\mathrm{NO}_{2(\mathrm{~g})}+\mathrm{CO}_{(\mathrm{g})} \longrightarrow \mathrm{NO}_{(\mathrm{g})}+\mathrm{CO}_{2(\mathrm{~g})}\) rate of reaction is proportional to square of [ \(\mathrm{NO}_2\) ] and independent of [CO].
What is the rate law equation?
- A \(r=k \frac{\left[\mathrm{NO}_2\right]^{\frac{1}{2}}}{[\mathrm{CO}]}\)
- B \(\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2[\mathrm{CO}]^0\)
- C \(\mathrm{r}=\frac{1}{2} \mathrm{k}\left[\mathrm{NO}_2\right][\mathrm{CO}]\)
- D \(\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2[\mathrm{CO}]\)
Answer & Solution
Correct Answer
(B) \(\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2[\mathrm{CO}]^0\)
Step-by-step Solution
Detailed explanation
The correct rate law equation is:
(B) \(r=k \times\left[\mathrm{NO}_2\right]^2 \times[\mathrm{CO}]^0\), which simplifies to \(r=k \times\left[\mathrm{NO}_2\right]^2\).
(B) \(r=k \times\left[\mathrm{NO}_2\right]^2 \times[\mathrm{CO}]^0\), which simplifies to \(r=k \times\left[\mathrm{NO}_2\right]^2\).
