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

The value of `K_(c)` for the reaction
`2A hArr B + C` is `2 xx 10^(-3)`. At a given time, the composition of reaction is `[A] = [B] = [C] = 3 xx 10^(-4) M`. In which direction the reaction will proceed?

Text Solution

Verified by Experts

For the reaction `2A hArr B+C`
`K_(c )=2.0xx10^(-3)(given)`
The reaction quotient `Q_(c )=([B][C])/([A]^(2))`
Substituting the value of A, B, and C, we get
`Q_( c)=((3xx10^(-4))(3xx10^(-4)))/((3xx10^(-4)))=1`
Since `Q_(c ) gt K_(c )`, therefore, the reaction will proceed in the backward direction.
