Can someone explain the difference between Q and K?

K is the equilibrium constant; Q is the concentration at the "initial stage" of the reaction, before equilibrium.

K is the equilibrium constant, while Q is the reaction quotient. K is determined only at chemical equilibrium, while Q can be evaluated at any stage. Only at equilibrium, Q=K. You can use the value of Q to see in which way will the reaction move towards.
