When two reactants A and B are mixed to ...

When two reactants `A` and `B` are mixed to give products, `C` and `D`, the reaction quotient `(Q)` at the initial stages of the reaction

A

is zero

B

decreases with time

C

is independent of time

D

increases with time

Text Solution

Verified by Experts

The correct Answer is:
D
Concentration of products increase with time so Q inceases.
`[:.Q=[[C][D]]/[[A][B]]]`

When two reactants A and B are mixed to give producys C and D, the reaction quotient (Q) at the initial stages of the reaction

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:

The reaction quotient (Q) predicts:
