\(KClO _3+6 FeSO _4+3 H _2 SO _4 \rightarrow KCl +3 Fe _2\left( SO _4\right)_3+3 H _2 O\) The above reaction was studied at \(300\,K\) by monitoring the concentration of \(FeSO _4\) in which initial concentration was \(10\,M\) and after half an hour became \(8.8\,M\). The rate of production of \(Fe _2\left( SO _4\right)_3\) is \(........\times 10^{-6}\,mol\,L ^{-1}\,s ^{-1}\).
- A \(332\)
- B \(331\)
- C \(336\)
- D \(333\)
Answer & Solution
Correct Answer
(D) \(333\)
Step-by-step Solution
Detailed explanation
\(KClO _3+6 FeSO _4+3 H _2 SO _4 \rightarrow KCl + 3 Fe _2\left( SO _4\right)_3+3 H _2 O\) \(ROR =-\frac{\Delta\left[ KClO _3\right]}{\Delta t }=\frac{-1}{6} \frac{\Delta\left[ FeSO _4\right]}{\Delta t }\)…
