For the reactions `A+BhArr3C` at `25^(@)C`, a 3 litre vessel contains 1,2,4 mole of A, B and C respectively predict the direction of reaction if
a. `K_(c)` for the reaction is 10
b. `K_(c)` for the reaction is 15
c. `K_(c)` for the reaction is 10.66

Explanation

`A+BhArr3C`
`Q=((4/3)^(3))/((1/3)(2/3))impliesQ=10.66`
a. `K_(c)` for the reaction is 10
`QgtK_(c)` so backward reaction takes place.
b. `K_(c)=15`
`QltK_(c)` forward reaction takes place.
c. `K_(c)=10.66`
`Q=K_(c)` Equilibrium is achieved.
