Equilibrium Constant Expression

Question

****Do not include states of matter, multiplication symbols, or spaces.

Use brackets [ ] to indicate concentration***

Write the equilibrium constant expression for each of the following reactions.

1. Al(OH)3(s) ----> Al3+(aq) +3OH-(aq)
2. 2Li+(aq) + CO3^2-(aq)----> Li2CO3(s)

Answer 1

(1). K = [Al³⁺][OH-]³ (note: since Al(OH)₃ is a solid, it is not included in the equilibrium expression

(2). K = 1 / [Li⁺]²[CO₃^2-] (note: since Li₂CO₃ is solid, it is assigned a value of 1)
