Identify the reaction related to Deacon's process

$$ 2 \mathrm{H}_2 \mathrm{O}+2 \mathrm{Cl}_2 \xrightarrow{\text { sunight }} 4 \mathrm{HCl}+\mathrm{O}_2 $$

$$ 4 \mathrm{HCl}+\mathrm{O}_2 \xrightarrow[723 \mathrm{~K}]{\mathrm{CuaC}_2} 2 \mathrm{Cl}_2+2 \mathrm{H}_2 \mathrm{O} $$

$$ 2 \mathrm{NaCl}+\mathrm{H}_2 \mathrm{SO}_4 \xrightarrow{823 \mathrm{~K}} \mathrm{Na}_2 \mathrm{SO}_4+2 \mathrm{HCl} $$

$$ \mathrm{Na}_2 \mathrm{~S}_2 \mathrm{O}_3+\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{Na}_2 \mathrm{SO}_4+2 \mathrm{HCl}+\mathrm{S} $$
