$\mathop {Salt\,\,'A'}\limits_{(Colourless)} \,\,\xrightarrow{{Cu}}$  Blue solution

$\mathop {Salt\,\,'A'}\limits_{(Colourless)} \,\,\xrightarrow[{(aq)}]{{HCl}}$ White ppt

$\mathop {Salt\,\,'A'}\limits_{(Colourless)} \,\,\xrightarrow[{{H_2}S{O_4}}]{{Conc.}}$ Brown fumes

$S\left( s \right) + {O_2}\left( g \right) \rightleftharpoons S{O_2}\left( g \right);{K_1} = {10^{52}}$

$2S\left( s \right) + 3{O_2}\left( g \right) \rightleftharpoons 2S{O_3}\left( g \right);{K_2} = {10^{129}}$

The equilibrium constant for the reaction $2S{O_2}\left( g \right) + {O_2}\left( g \right) \rightleftharpoons 2S{O_3}\left( g \right)$ is

$(A)$ $n=3,1=0, m=0$

$(B)$ $n=4,1=0, m=0$

$(C)$ $n =3,1=1, m =0$

$(D)$ $n=3,1=2, m=1$
