Consider the reaction `2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g)` for which `K_(c)=278M^(-1)`.0.001 mole ofeach of the reagents `SO_(2)(g),O_(2)(g)and SO_(3)(g)` are mixed in a 1.0 L flask . Dterminr=e the reaction quotient of the system and the spontaneus direction of the system:

A

`Q_(c)` = 1000, the equilibrium shifts to the right

B

`Q_(c)` 1000, the equilibrium shifts to the left

C

`Q_(c)`= 0.001, the equilibrium shifts to the left

D

`Q_(c)`= 0.001, the equilibrium shifts to the right

Text Solution

Verified by Experts

The correct Answer is:
B
`Q_(C)=([SO_(3)(g)]^(2))/([SO_(2)(g)]^(2)[O_(2)(g)]^(1))=1000gtK_(c)`
i.e., reaction moves backward also if volume increases pressure decreases
`impliesQ_(c)uarr`.
