### reaction quotient

Are we always calculating Q when we don't know whether or not the reaction has reached equilibrium?

Q, the reaction quotient, measures the amounts of reactants and products during a reaction at a specific point in time, and can be calculated before the reaction reaches equilibrium. So if the reaction has not reached equilibrium yet, the product/reactant ratio is Q, and is giving information that can be compared to K.

Q, a variable, describes the same reactant-product relationship as K, except K is a constant where Q=K would represent the reaction at equilibrium.

### Re: reaction quotient

if you calculate q and it equals k then it is at equilibrium. If they don't equal, then it's not and the reaction is still occurring. From there you can compare q and k to determine which way the reaction will proceed to reach equilibrium.

usually if we're asked to calculate Q then a K value should be provided to help us determine if it has reached equilibrium
