(b) \(5 \mathrm{Br}^{-}(a q)+\mathrm{BrO}_{3}^{-}(a q)+6 \mathrm{H}^{+}(a q) \rightarrow 3 \mathrm{Br}_{2}(a q)+3 \mathrm{H}_{2} \mathrm{O}(\mathrm{l})\)
ANSWER:
Step 1 of 3
The rate expression for a chemical reaction can be expressed in terms of the disappearance of the left-side term (reactants) and the appearance of the products (products).
A negative sign is placed for reactant term as concentration for the reactant goes on decreasing. The stoichiometric for each term goes in a fraction.
