- A \(0.026 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
- B \(0.052 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
- C \(0.078 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
- D \(0.114 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
Answer & Solution
Correct Answer
(A) \(0.026 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
Step-by-step Solution
Detailed explanation
\(-\frac{\mathrm{d}\left[\mathrm{O}_2\right]}{\mathrm{dt}} =\frac{1}{2} \frac{\mathrm{d}\left[\mathrm{NO}_2\right]}{\mathrm{dt}} \)
\( =\frac{1}{2} \times 0.052 \)
\( =0.026 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
\( =\frac{1}{2} \times 0.052 \)
\( =0.026 \mathrm{~mol} \mathrm{dm}^{-3} \mathrm{~s}^{-1}\)
