### Q vs. K

What exactly is the difference between the reaction quotient, Q, and the equilibrium constant, K? Also, what’s the difference in terms of solving for them?

### Re: Q vs. K

Q can be the concentrations of the reactants and products at any point in the reaction. K can only be the concentrations of the reactants at equilibrium. You go about solving them the same way. By using both Q and K, we can determine which way the reaction is more likely to proceed.

### Re: Q vs. K

So it is possible for Q and K to be equal, if Q is at equilibrium?

Yes! If Q and K are equal, we know that the mixture has equilibrium composition and has no tendency to change in either direction.
