\end{matrix}\,$ $\xrightarrow{{{H}_{2}}O/{{H}^{\oplus }}}$ $\underset{Major\,\,product}{\mathop{A}}\,$ $+$ $\underset{Major\,\,product}{\mathop{B}}\,$
The major product is
(At. nos. $Mn = 25, Fe = 26, Co = 27, Ni = 28$)
${O_3}(g)\, + \,C{l^ * }(g)\, \to \,{O_2}(g) + Cl{O^ * }(g)$ ..... $(i)$ $[{K_i} = 5.2 \times {10^9}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
$Cl{O^ * }(g) + {O^ * }(g)\, \to \,{O_2}(g) + \,C{l^ * }(g)$ ..... $(ii)$ $[{K_{ii}} = 2.6 \times {10^{10}}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
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 ........... $L\,\,mo{l^{ - 1}}\,{s^{ - 1}}$
$\mathrm{Pt}(s) \mid \mathrm{H}_2(g, 1 \text { bar })\left|\mathrm{H}^{+}(a q, 1 \mathrm{M}) \| \mathrm{M}^{4+}(a q), \mathrm{M}^{2+}(a q)\right| \mathrm{Pt}(s)$
$E_{\text {cell }}=0.092 \mathrm{~V} \text { when } \frac{\left[\mathrm{M}^{2+}(a q)\right]}{\left[\mathrm{M}^{4+}(a q)\right]}=10^x$
Given : $ E_{\mathrm{M}^4 / \mathrm{M}^{2+}}^0=0.151 \mathrm{~V} ; 2.303 \frac{R T}{F}=0.059 \mathrm{~V}$
The value of $x$ is
$2{X_2}\left( s \right) + 3{Y^{ + 2}}\left( {aq} \right) \to 2X_2^{3 + }\left( {aq} \right) + 3Y\left( s \right)$
