What is the rate of disappearance of B in following reaction? \(2 \mathrm{~A}+\mathrm{B} \rightarrow 3 \mathrm{C}\), if rate of appearance of \(\mathrm{C}\) is \(1.3 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\).
- A \(4.33 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
- B \(8.6 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
- C \(2.6 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
- D \(5.2 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
Answer & Solution
Correct Answer
(A) \(4.33 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
Step-by-step Solution
Detailed explanation
\(\frac{\text { Rate of disappearance of B }}{1}=\frac{\text { Rate of appearance of } \mathrm{C}}{3}\)
Rate of disappearance of B \(=\frac{1}{3} \times 1.3 \times 10^{-4}\)
\(=4.33 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
Rate of disappearance of B \(=\frac{1}{3} \times 1.3 \times 10^{-4}\)
\(=4.33 \times 10^{-5} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\)
