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) 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)` will remain unchanged

Answer

C

Explanation

An increase in volume for the equilibrium having, `K _(c) = ([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.
