Chemical equilibrium is attained in a reversible reaction carried in a close container and is of dynamic nature. The value of equilibrium constant may be expressed either as `K_(p)" and " K_(c)` and the two are related to each other as :
`K_(p) =K_(c)(RT)^(Deltang)`
Free energy change `(DeltaG)` at equilibrium point is zero. The value of equilibrium constant gives the extent to which a particular reation has proceeded to attain the equilibrium . Its value gets reversed if the reaction is reversed and becomes the square root of the initial value if the reaction is divided by 2.
when the two reactants A and B are mixed to give products C and D , the reaction quotient Q at initial stage of the reaction:

Options

A. is zero
B. decreases with time
C. is independent of time
D. increases with time

Answer

D

Explanation

`Q=[[C][D]]/[[A][B]]`
Since the molar concentration of products increases while that of the reactants decreases the value of Q increases with time.
