Question

please explain well. I don't understand at all. Explain all steps ans math involved.

3. Elemental sulfur is a molecular solid. The most stable allotrope of elemental sulfur is actually the eight-membered ring, Ss. Thus, the elemental sulfur in the H2S formation reaction shown in question 1 should actually be written as Sa(s). Use the equilibrium constant given in question 1 to find K for the following reaction: 8H2(g) + S«(s) - 8H2S(8) K ?
