Write the equilibrium constant expression for the reaction below.

CS2 (g) + 4H2O (g) ⇌ CH4 (g) + 2H2S (g)

Kc = [H₂S]². [CH₄] / [ H₂O]⁴. [CS₂]

Explanation:

The equilibrium constant indicates the % of the yield reaction and can shows where the reaction is going to be equilibrated.

It works with molar concentrations on the equilibrium and it does not consider the solids compounds

Kc also can be modified by the time of the reaction.

This reaction is:

CS₂ (g) + 4 H₂O (g) ⇌ CH₄ (g) + 2H₂S (g)

Kc = [H₂S]². [CH₄] / [ H₂O]⁴. [CS₂]
