![### Reaction Rate Calculation Problem
Consider the following reaction in aqueous solution:
\[ 5\text{Br}^-_{(aq)} + \text{BrO}_3^-_{(aq)} + 6\text{H}^+_{(aq)} \rightarrow 3\text{Br}_2{_{(aq)}} + 3\text{H}_2O_{(l)} \]
If the rate of appearance of \(\text{Br}_2{_{(aq)}}\) at a particular moment during the reaction is \(0.00035 \, \text{M} \, \text{s}^{-1}\), what is the rate of appearance of \(\text{H}_2O_{(l)}\) at that moment?
#### Multiple Choice Options:
1. \(2.1 \times 10^{-4} \, \text{M} \, \text{s}^{-1}\)
2. \(2.0 \times 10^{-4} \, \text{M} \, \text{s}^{-1}\) (Correct answer, highlighted)
3. \(1.1 \times 10^{-3} \, \text{M} \, \text{s}^{-1}\)
4. \(1.8 \times 10^{-3} \, \text{M} \, \text{s}^{-1}\)
### Explanation:
To find the rate of appearance of \(\text{H}_2O{_{(l)}}\), we need to relate the rates of appearance of \(\text{Br}_2{_{(aq)}}\) and \(\text{H}_2O_{(l)}\) through their stoichiometric coefficients in the balanced chemical equation.
In the reaction, 3 moles of \(\text{Br}_2{_{(aq)}}\) are produced per 3 moles of \(\text{H}_2O_{(l)}}\):
\[
\text{Rate of appearance of } \text{H}_2O_{(l)} = \left( \frac{3 \, \text{moles H}_2O}{3 \, \text{moles Br}_2} \right) \times \text{Rate of appearance of } \text{Br}_2
\]
Since the ratio simplifies to 1:1:
\[
