k > 1 :: ___ are favored
k < 1 :: ___ are favored
k ≈ 1 :: both are favored ___.
___ of K tells us what is favored at equilibrium.
if k is super big: forward reaction ___ to ___.
if k is super small: forward reaction ___ takes ___.
Answer explanation
k > 1 :: products are favored
k < 1 :: reactants are favored
k ≈ 1 : both are favored equally
Magnitude of K tells us what is favored at equilibrium.
if k is super big : forward reaction goes to completion.
if k is super small: forward reaction barely takes place.
products, reactants, equally, magnitude, goes, completion, barely, place
