  • Rate Laws

Equilibrium

  • Equilibrium Reactions RxN ⇄
  • Equilibrium Constants
  • Equilibrium Expression: [tex]\displaystyle K = \frac{[Producst]^{coefficients}}{[Reactants]^{coefficients}}[/tex]

Explanation:

*Note: Only gases and liquids affect equilibrium

Step 1: Define

[RxN - Balanced] 2H₂O (g) ⇄ 2H₂ (g) + O₂ (g)

Step 2: Identify

[Reactant] H₂O

  • Coefficient of 2

[Product] H₂

  • Coefficient of 2

[Product] O₂

  • Coefficient of 1

Step 3: Write K Expression

  1. Substitute:                                                                                                       [tex]\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}[/tex]
