How do we know which way the equilibrium will shift?

It depends on what is changing in the reaction. If the number of moles are changing, the rxn will shift a certain way in order to get the system back to equilibrium. If the product is taken away, then equilibrium will shift towards the products and if product is added, equilibrium will shift towards the reactants. Equilibrium also shifts with changes in pressure and temperature.

For more clarification on your question, are you asking about how Le Chatelier's works?

If you are referring to K value vs Q value:
When Q>K, the rxn will shift to the left, creating more reactants
When Q<K, the rxn will shift to the right, creating more products

There are multiple different ways an equilibrium can shift- if reactants are added to a reaction, the reaction will naturally want to balance itself to fit the reaction constant and thus will create more products. The same applies vice-versa.

It depends on the circumstance but in general, the reaction will shift in the direction that allows for it to reach equilibrium. For example, if Q (reaction quotient)<K(equilibrium constant) the reaction will shift to the right because the concentration of reactants is greater than the concentration of products.

if K>Q the reaction shifts in favor of the products
if K<Q the reaction shifts in favor of the reactants
