AP Chemistry / Unit 7: Equilibrium
7.5 Magnitude of the Equilibrium Constant
Notes
- $K\gg1$: products favored.
- $K\ll1$: reactants favored.
- $K\approx1$: significant amounts of both.
Practice
$K=2\times10^{8}$. At equilibrium the mixture is mostly:
Huge $K$.
$K=10^{-5}$ means:
Small $K$.
The size of $K$ tells you about:
Not about speed.
