The difference between Q and $K_{sp}$ is no differencé. $K_{sp}$ is the value of the product at equilibrium and Q is the value of the product under any condition. Q is the value of the product at equilibrium and $K_{sp}$ is the value of the product under any condition. Q is greater than $K_{sp}$ $K_{sp}$ is greater than Q.
