Question

1a)

For the reaction

2CH4(g)⇌C2H2(g)+3H2(g)

Kc = 0.135 at 1733 ∘C . What is Kp for the reaction at this temperature?

1b)

For the reaction

N2(g)+3H2(g)⇌2NH3(g)

Kp = 5.20×10⁻³ at 270. ∘C . What is Kc for the reaction at this temperature?

1c)

Given the two reactions

1. H2S⇌HS−+H+,   K1 = 9.74×10⁻⁸, and
2. HS−⇌S2−+H+,   K2 = 1.53×10⁻¹⁹,

what is the equilibrium constant Kfinal for the following reaction?

S2−+2H+⇌H2S

1d)

Given the two reactions

3. PbCl2⇌Pb2++2Cl−,   K3 = 1.86×10⁻¹⁰, and
4. AgCl⇌Ag++Cl−,   K4 = 1.19×10⁻⁴,

what is the equilibrium constant Kfinal for the following reaction?
