This suggests that for every molecule of N2O5 that disappears, two molecules of NO2 appear and one molecule of O2 appears. This corresponds to the balanced chemical equation: Show more…

Reaction rate is expressed in terms of changes in concentration of reactants and products. Write a balanced equation for $$ \text {(Rate)} =-\frac{1}{2} \frac{\Delta\left[\mathrm{N}_{2} \mathrm{O}_{5}\right]}{\Delta t}=\frac{1}{4} \frac{\Delta\left[\mathrm{NO}_{2}\right]}{\Delta t}=\frac{\Delta\left[\mathrm{O}_{2}\right]}{\Delta t} $$
Write a rate equation, showing the dependence of rate on reactant concentrations, for each of the following elementary reactions. a. $\mathrm{} \mathrm{O}_{3} \longrightarrow \mathrm{O}_{2}+\mathrm{O}$ b. $\mathrm{NOCl}_{2}+\mathrm{NO} \longrightarrow 2 \mathrm{NOCl}$
Express the rate of reaction in terms of the rate of change of each reactant and each product in the following equations. (a) $3 \mathrm{ClO}^{-}(\mathrm{aq}) \longrightarrow \mathrm{ClO}_{3}^{-}(\mathrm{aq})+2 \mathrm{Cl}^{-}(\mathrm{aq})$ (b) $2 \mathrm{SO}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{SO}_{3}(\mathrm{~g})$ (c) $\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{~g})+\mathrm{Br}_{2}(\mathrm{~g}) \longrightarrow \mathrm{C}_{2} \mathrm{H}_{4} \mathrm{Br}_{2}(\mathrm{~g})$ (d) $\left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2}(\mathrm{NH})_{2}+\mathrm{I}_{2} \longrightarrow\left(\mathrm{C}_{2} \mathrm{H}_{5}\right)_{2} \mathrm{~N}_{2}+2 \mathrm{HI}$ (liquid phase)
