The value of K(c) for the reaction 2AhAr...

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 ?

Text Solution

Verified by Experts

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) lt K_(c)` so the reaction wil proceed in the reverse direction.
