what does the reaction quotient tells us about the equilibrium reaction?

If Q is less than K at some point during the reaction, then the forward reaction is favored while if Q is greater than K at some point during the reaction, the reverse reaction is favored.

Q taken at any point when the reaction is not at equilibrium indicates the direction that will be favored by the reaction. If Q is less than Kc, then there is an excess of reactants, and product will be created to balance that amount out. The same goes vice versa if Q is greater than Kc leading to more reactant being formed.

Comparing the reaction quotient to K tells us which direction of the reaction is favored. So if Q>K then the reverse reaction is favored since this means that there are more products than reactants in the nonequilibrium concentration Q. If Q<K, then the forward reaction is favored since this means that there are more reactants than products in the nonequilibirum concentration Q.

The reaction quotient tells us which direction the reaction will proceed to reach equilibrium. If Q<K, then there are less products than would be found in the equilibrium reaction so the reaction proceeds in the forward direction. By the same logic, if Q>K, then there are more products than would be found in the equilibrium reaction so the reaction proceeds in the reverse direction.

If Q < K, then there are not enough product, so reaction goes forward.
If Q>K, then there are not enough reactants, to reaction goes backward.

It tells us whether there is more reactant or product during the reaction. And with that, it can determine whether a forward or reverse reaction is favored. So if Q is smaller than K, then there is more reactant than product, resulting in favoring a forward reaction. If K is smaller than Q, then there is more product than reactant, resulting in favoring a reverse reaction.
