Question

For the reaction, `A+BhArr3C`, at `25^(@)C`, a `3 litre` vessel contains `1`, `2`, `4mol es` of `A`, `B` and `C` respectively. If `K_(c)` for the reaction is `10`, the reaction will proceed in :
A. Forward direction
B. Backward direction
C. In either direction
D. In equilibrium

Answer 1

Correct Answer - B
`Q = ([C]^(3))/([A][B]) = (4^(3)xx3xx3)/(3^(3)xx1xx2) = 10.66`
`.: [C] = (4)/(3)`
`[A] = (1)/(3) [B] = ((2)/(3))`
`.: K_(C) = 10` , and `Q gt K_(C)`
`:.` reaction will proceed in backward direction.
