Question $3$

Consider the reaction $2S{O}_2(g)+O_2(g)2S{O}_3(g).$

A mixture is prepared that initially contains only $S{O}_3$ and $O_2$ gases. After some time, the reaction produces an equilibrium mixture of $S{O}_2,S{O}_3$ and $O_2$

gases. Which of the following is the most appropriate change line in the corresponding ICE table?

$($A$)$

$($B$)$

$($C$)$

A
