Statement $I$: Aqueous solution of $K _2 Cr _2 O$, is preferred as a primary standard in volumetric analysis over $Na _2 Cr _2 O$, aqueous solution
Statement $II:$ $K _2 Cr _2 O$, has a higher solubility in water than $Na _2 Cr _2 O _7$
In the light of the above statements, choose the correct answer from the options given below:
$S\left( s \right) + {O_2}\left( g \right) \rightleftharpoons S{O_2}\left( g \right);{K_1} = {10^{52}}$
$2S\left( s \right) + 3{O_2}\left( g \right) \rightleftharpoons 2S{O_3}\left( g \right);{K_2} = {10^{129}}$
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
