Determining Equilibrium Reaction Direction

[Giselle Littleton 1F]

When determining the direction of an equilibrium reaction, how do you know whether to use 10^3/10^-3 or 1 as a comparison to K? I've seen both 1 and 10^3/10^-3 being used.

Hopefully what I say helps but from the video modules that he sent to us on his website, he mentioned how if k > 10^3, it means that the equilibrium STRONGLY favors the products meanwhile if k > 1, it favors the products too but only SLIGHTLY. But one thing that they have in common is that they favor the products, and this concept would be the same for if k < 10^-3 and k < 1

So you can use either one^

So would anything between k > 10^3 and k > 1 be only slight favoring?

Yea, I would assume so
