Write the equilibrium-constant expression for the reaction shown in terms of [SO2], [CO2]. [CS2], [O2].

Question

Write the equilibrium-constant expression for the reaction shown in terms of [SO₂], [CO₂]. [CS₂], [O₂].

2 SO₂ (g) + CO₂ (g) ⇌ CS₂ (g) + 3 O₂ (g)

K_c , which is sometimes symbolized as K or K_{eq ,} denotes that the equilibrium constant is expressed using molar concentrations. For this question, K_c means the same thing as K and K_eq.

K_c= ?

Answer 1

K_c = [CS₂][O₂]³

[SO₂]²[CO₂]
