Chemistry: Introducing Inorganic, Organic and Physical Chemistry

Write the rate equation for the following elementary reactions and give the molecularity for each reaction. (Sections 9.4 and 9.8)

(a) $\mathrm{Cr}+\mathrm{O}_{3} \rightarrow \mathrm{ClO}^{*}+\mathrm{O}_{2}$

(b) $\mathrm{CH}_{3} \mathrm{N}_{2} \mathrm{CH}_{3} \rightarrow 2 \mathrm{CH}_{3}^{*}+\mathrm{N}_{2}$

(c) $2 \mathrm{Cl}^{\prime} \rightarrow \mathrm{Cl}_{2}$

(d) $\mathrm{NO}_{2}^{*}+\mathrm{F}_{2} \rightarrow \mathrm{NO}_{2} \mathrm{F}+\mathrm{F}$
