Consider the following reaction where K = 55.6 at 698 K: H2(g) + 2(g) 2HI(g) A reaction mixture was found to contain 2.61×102 moles of H2(g), 3.63×10-2 moles of 12(g) and 0.279 moles of HI(g), in a 1.00 Liter container. Indicate True (T) or False (F) for each of the following: 1. In order to reach equilibrium HI(g) must be produced. F 2. In order to reach equilibrium K must decrease. TV3. In order to reach equilibrium H₂ must be produced. T4. Qc is greater than Kr. F5. The reaction is at equilibrium. No further reaction will occur. The equilibrium constant, Kc, for the following reaction is 1.80 × 10-4 at 298 K. NH HS(s) NH3 (g) + H2S(9) Calculate the equilibrium concentration of H2S when 0.456 moles of NH4HS(s) are introduced into a 1.00 L vessel at 298 K. [H2S]=0.00897 M
