The value of `K_(c)` for the reaction `2AhArrB+C` is `2xx10^(-3)`. At a given time, the composition of reaction mixture is `[A]=[B]=[C]=3xx10^(-4)M`. In which direction the reaction will proceed ?

Explanation

For the reaction the reaction quotient `Q_(C)` is given by.
`Q_(C)=[B][C]//[A]^(2)`
`as [A]=[B]=[C]=3xx10^(-4)M`
`Q_(C)=(3xx10^(-4))(3xx10^(-4))//(3xx10^(-4))^(2)=1`
as `Q_(C) gt K_(C)` as the reaction will proced in the reverse direction.
