Re: Q and Ke: Small K value and Large K value
The reaction quotient or Q is the ratio of the products over the reactants at whatever time you calculated the concentrations at. We then compare this ratio to the known K value or equilibrium constant to see if the reaction is still going and in what direction.

Re: Q and Ke: Small K value and Large K value
Q is the value of products over reactants at any given time in the equation. K is the value of products over reactants when the reaction has reached equilibrium.

Re: Q and Ke: Small K value and Large K value
The reaction quotient, Q, is calculated in the same way in which K is calculated. If Q < K, the reaction is proceeding forward, toward products. If Q > K, the reaction is proceeding in reverse, toward reactants.
Re: Q and Ke: Small K value and Large K value
If Q is less than K this tells you that products still need to form, so the reaction will go forward.
If Q is greater than K it tells you that there are more products and the reaction must go back towards the reactants.
If Q is greater than K it tells you that there are more products and the reaction must go back towards the reactants.

Re: Q and Ke: Small K value and Large K value
Q changes based on where the reaction is, whereas K does not change except when temperature changes.
Re: Q and Ke: Small K value and Large K value
The reaction quotient is the amount of products over reactants at any time during the Rxn, it is calculated the same way as K but it is not at equilibrium.
Re: Q and Ke: Small K value and Large K value
the reaction quotient is basically the equilibrium constant at a moment where the reaction is not at equilibrium. It can provide insight into which direction the reaction will proceed.
