So if you’re looking at a graph, the favored rxn is forward if product amount is higher at equilibrium, or the reverse rxn is favored if the reactant amount is higher at equilibrium.
You can tell through looking at the K value by seeing if it’s a large number, product is favored which means the forward rxn is favored, but if it’s smaller that means he reactant is favored, meaning the reverse rxn is favored.
