$\mathrm{C}_2 \mathrm{H}_5 \mathrm{I}_{(\mathrm{g})} \longrightarrow \mathrm{C}_2 \mathrm{H}_{4(\mathrm{~g})}+\mathrm{HI}_{(\mathrm{g})}$

$2 \mathrm{NO}_2 \mathrm{Cl}_{(\mathrm{g})} \longrightarrow 2 \mathrm{NO}_{2(\mathrm{z})}+\mathrm{Cl}_{2(\mathrm{z})}$

$2 \mathrm{NO}_{2(\mathrm{~g})}+\mathrm{F}_{2(\mathrm{~g})} \longrightarrow 2 \mathrm{NO}_2 \mathrm{~F}_{(\mathrm{g})}$

$ 2 \mathrm{NO}_{(\mathrm{g})}+\mathrm{Cl}_{2(\mathrm{g})} \longrightarrow 2 \mathrm{NaCl}_{(\mathrm{g})}$
