artcher [175]

<h3>Answer:</h3>

$\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$

<h3>General Formulas and Concepts:</h3>

<u>Chemistry</u>

<u>Aqueous Solutions</u>

States of matter

<u>Kinetics</u>

Rate Laws

<u>Equilibrium</u>

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

<h3>Explanation:</h3>

*Note: Only gases and liquids affect equilibrium

<u>Step 1: Define</u>

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

<u>Step 2: Identify</u>

[Reactant] H₂O

Coefficient of 2

[Product] H₂

Coefficient of 2

[Product] O₂

Coefficient of 1

<u>Step 3: Write K Expression</u>

Substitute: $\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$
