A reaction `S_(8)(g) hArr 4S_(2)(g)` is carried out by taking `2` mol of `S_(8)(g)` and `0.2` mol of `S_(2)(g)` is a reaction vessel of `1 L`. Which one is not correct if `K_(c)=6.30xx10^(-6)`

Options

A. Reaction quotient is `8.0xx10^(-4)`
B. `K_(p)=2.55 atm^(3)`
C. Reaction proceeds in forward direction
D. Reaction proceeds in backward direction

Explanation

(a,b,d)
`Q=([S_(2)]^(4))/([S_(8)])=((0.2)^(4))/((2))=8.0xx10^(-4)`
`:' K_(c)=6.3xx10^(-6)`
`:. K_(p)=K_(c)xx(RT)^(Deltan)`
`=6.3xx10^(-6)xx(0.0821xx900)^(3)=2.55 atm^(3)`
Thus, reaction proceeds in backward direction, since `QgtK_(c)`
