If an equation is reversed, what happens to the equilibrium constant KK?

It becomes the reciprocal: 1/K1/K

If all coefficients in an equation are doubled, what happens to KK?

It is squared: (Koriginal)2(K_{\text{original}})^2

What does a large KK value (greater than 10410^4) indicate about a reaction?

Products dominate at equilibrium

What does a small KK value (less than 10410^{-4}) indicate?

Very little reaction occurs

A reaction has K=0.52K = 0.52. Which category does this fall into?

Intermediate (appreciable amounts of both)

Why is carbon monoxide highly toxic to haemoglobin?

KK for CO binding is ~20,000 times larger

Which concentrations must be used to calculate KK?

Equilibrium concentrations only

Acetic acid has K=1.8×105K = 1.8 \times 10^{-5} M. What type of acid is it?

Weak acid (only partially dissociates)

In an ICE table, what does 'ICE' stand for?

Initial, Change, Equilibrium

How can you find an unknown equilibrium concentration if you know KK?

Rearrange the equilibrium expression
