${O_3}(g)\, + \,C{l^ * }(g)\, \to \,{O_2}(g) + Cl{O^ * }(g)$ ..... $(i)$ $[{K_i} = 5.2 \times {10^9}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
$Cl{O^ * }(g) + {O^ * }(g)\, \to \,{O_2}(g) + \,C{l^ * }(g)$ ..... $(ii)$ $[{K_{ii}} = 2.6 \times {10^{10}}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
The closest rate constant for the overall reaction
${O_3}(g){\mkern 1mu} + {\mkern 1mu} {O^*}(g){\mkern 1mu} \to {\mkern 1mu} 2{O_2}(g)$ is ........... $L\,\,mo{l^{ - 1}}\,{s^{ - 1}}$
