Nitrogen monoxide and hydrogen react to form nitrogen and water, like this: 2NO+2 H2 (g) - N29) + 2H2O (9) Write the pressure equilibrium constant expression for this reaction

Partial pressure N₂. (Partial pressure H₂O) ² / (Partial pressure H₂) ². (Partial pressure NO) ² = Kp

Explanation:

The reaction is:

2NO + 2H₂ → N₂ + 2H₂O

The expression for Kp (pressure equilibrium constant) would be:

Partial pressure N₂. (Partial pressure H₂O) ² / (Partial pressure H₂) ². (Partial pressure NO) ²

There is another expression for Kp, where you work with Kc (equilibrium constant)

Kp = Kc (R. T) ^Δn

where R is the Ideal Gases constant

T° is absolute temperature

Δn = moles of gases formed - moles of gases, I had initially
