Question

Select all of the correct statements about reaction quotients and equilibrium constants from the choices below.

A reaction quotient equals the equilibrium constant at equilibrium.

The value of K does not change as a reaction progresses toward equilibrium.

As a reaction approaches equilibrium its Q value rises and its K value falls until they are equal.

As concentrations change Q changes, whereas K stays constant.

As a reaction progresses forward toward equilibrium K rises until it reaches Q.

If Q > K the reaction must progress forward to attain equilibrium.

for a reaction A+B--->C Q =reaction coefficient and K= equilibrium constnat

Q= [C]/ [A]/[B] and K= [C]/ [A][B]

At equilibrium Q= K

The value of K is defined at equilibrium and hence for a given reaction it is fixed.

It is not possible to say Q value rises or decreases and K values remains constant

With change in concentration Q changes , but K remains constant

if Q< K the reaction must progress forward to attain equilibbrium
