Mass action ratio or reaction quotient Q...

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. For the reaction : `2A+BhArr3C` at 298 K, `K_(c)=49` A 3 L vessel contains 2, 1 and 3 moles of A, B and C respectively. The reaction at the same temperature :

A

must proceed in forward direction.

B

must proceed in back direction

C

must be predicted

D

cannot be predicted
