Question

Write the pressure equilibrium constant expression for this reaction. 2CO2 (g) + 4H2O (g) → 2CH3OH (l) + 3O2 (g)

Answer 1

The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.

Step-by-step explanation:

• For the reaction:

2CO₂ (g) + 4H₂O (g) → 2CH₃OH (l) + 3O₂ (g).

The pressure equilibrium constant (Kp) = the product of the pressure of the products side components / the product of the pressure of the reactantss side components.

each one is raised to a power equal to its coefficient.

∴ The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.
