2 H₂(g) + S₂(g) ⇌ 2 H₂S(g) …… Kc = 1.30 × 10¹⁰
At equilibrium:
Kc = [H₂S]² / ([H₂]² [S₂])
1.30 × 10¹⁰ = [H₂S]² / (0.00500² × 0.00230)
[H₂S] = √{(1.30 × 10¹⁰) × 0.00500² × 0.00230} M = 27.3 M
At equilibrium:
Kc = [H₂S]² / ([H₂]² [S₂])
1.30 × 10¹⁰ = [H₂S]² / (0.00500² × 0.00230)
[H₂S] = √{(1.30 × 10¹⁰) × 0.00500² × 0.00230} M = 27.3 M
