For the reaction, A+BhArr3C, at 25^(@)C,...

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

Text Solution

Verified by Experts

The correct Answer is:
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.

Mass action ratio or reaction quotient Q for a reaction can be calculated using the law of mass actionl, A(g)+B(g)hArrC(g)+D(g) Q=([C][D])/([A][B]) The value of Q decides whether the reaction is at equilibrium or not. At equilibrium, Q=K For non-equilibrium process QneK When QgtK , reaction will be favoured in backward direction and when QltK , it will be favoured in forward direction.
