$K _{ p }=\frac{ P _{ SO _3}^2}{ P _{ SO _2}^2 \times P _{ O _2}}=\frac{(0.331)^2}{(0.662)^2 \times 0.101}=\frac{1}{0.404}$

હવે $P _{ SO _2}= P _{ SO _3}$

$K _{ p }=\frac{ P ^2 / O _3}{ P ^2 / O _2 \times P _{ O _2}} \quad \therefore \frac{1}{0.404}=\frac{1}{ P _{ O _2}} \therefore P _{ O _2}=0.404$

$\begin{array}{cccc} A + B & \rightleftharpoons & C + D \\ x & x & 0 \\ x - a & a & a \end{array}$

સંતુલને $2|A|=|D|$

$2(x-a)=a$

$\therefore x=3 a / 2$

$\therefore| A |=| B |= x - a =\frac{3 a}{2}-\frac{a}{2}=\frac{a}{2}$

$K_C=\frac{|C||D|}{| A || B |}=\frac{a \times a}{\frac{a}{2} \times \frac{a}{2}}=4$
