Im chemistry, what does it mean if the products or the reactants are favored? favored to what?

In most chemical reactions the reactants combine to form
one or more products and the reaction goes to completion. that means the reactants are
all used up and you only have product(s).

However, in some
chemical reactions, an equilibrium occurs where there are both reactants and products
present.  An example of this is the reaction of N2 + H2 to form NH3.  This reaction
takes place under high temperature and pressure and there is always a combination of all
three substances present.

In an equilibrium reaction if
there are more products present than reactants the reaction favors the
products.

If there are more reactants than products then
the reaction favors the reactants.
