Please help i need to get these right in order to get an A PLEASE PLEASE PLEASE 1. What is the Kc for the following reaction at equilibrium at 1000 ∘C if [CO]= 0.50 M , [H2]= 0.32 M , [CH4]= 1.6 M , and [H2O]= 2.8 M ? CO(g)+3H2(g)⇌CH4(g)+H2O(g) 2. The equilibrium constant, Kc, for the reaction of H2 and N2 is 1.7×102 at 225 ∘C. 3H2(g)+N2(g)←−→2NH3(g) If the system at equilibrium contains 0.19 M H2 and 0.026 M...

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 ? 1. Ammonia and hydrogen sulfide...
