What is the difference between reaction quotient (Q) and equilibrium constant (K) of a reaction?

The equilibrium constant (K_(P)) of a gaseous reaction is-

Write the relation betweenn DeltaG^(0) and the equilibrium constant (K) for a reaction at TK. Using this relation state that for what value of DeltaG^(0) , the value of K will be K gt 1, K lt 1 , K=1 .

The equilibrium constant (K) of a reaction may be written as

What is difference between chemical reaction and nuclear reaction ?

The equilibrium constant (k) of a reaction may be written as

What does it imply about the direction of a reactions, if the value of reaction quotient (Q) at any instant of the reaction at a constant temperature is smaller than or larger than or equal to the equilibrium constant (K) of the reaction at the temperature?

Which one is correct for equilibrium constant of a revessible reaction—

The equilibrium constant of a reversible reaction at a particular temperature is K. What Will be the values of reaction quotient ( Q) at the beginning and at equilibrium of the reaction?

At a given temperature, for the reaction AhArrB , the rate constant (k_(f)) of the forward reaction is greater than that of the backward reaction (k_(b)) . Is the value of equilibrium constant (K) for this reaction greater than, less than or equal to 1?
