Question

What is the equilibrium constant expression for the given system?

Answer 1

B.

Step-by-step explanation:

I don’t know the explanation but it’s right oh edg

Answer 2

`\displaystyle K_(eq) = ([H_2]^2[O_2])/([H_2O]^2)`

General Formulas and Concepts:

Chemistry

Aqueous Solutions

• States of matter

Kinetics

• Rate Laws

Equilibrium

• Equilibrium Reactions RxN ⇄
• Equilibrium Constants
• Equilibrium Expression:
  `\displaystyle K = ([Producst]^(coefficients))/([Reactants]^(coefficients))`

Step-by-step 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:
   `\displaystyle K_(eq) = ([H_2]^2[O_2])/([H_2O]^2)`
