The volume of the reaction vessel containing an equilibrium mixture in the reaction,
`SO _(2) CL _(2 (g) )hArr SO _(2 _(g)) + Cl _(2 (g)) ` is increased. When equilibrium is re-established:

Options

A. the amount of `SO_(2(g))` will decrease
B. the amount of `SO_(2)Cl_(2(g))` will increase
C. the amount of `Cl_(2(g))` will increase
D. the amount of `Cl_(2(g))` will remain unchaned

Answer

C

Explanation

An increase in volume for the equilibrium having `K_(o) = ([SO_(2)][Cl_(2)])/([SO_(2)Cl_(2)]) = (["mole of "SO_(2)]["mole of " Cl_(2)])/(["mole of " SO_(2)Cl_(2)] xx "volume")` will increase the mole of `Cl_(2)` or `SO_(2)` to maintain `K_(c )` values constant.
