Hydrogen sulfide decomposes according to the following reaction, for which Kc = 9.30 10-8 at 700°C. 2 H2S(g) 2 H2(g) + S2(g) If 0.33 mol H2S is placed in a 4.7 L container, what is the equilibrium concentration of H2(g) at 700°C? M
H2 and Cl2 combine to form HCl. In a gas phase equilibrium mixture of H2, Cl2, and HCl at 300 K, [HCl] = 0.0036 mol/L and [Cl2] = 0.00485 mol/L.
A rigid flask is initially filled with 4.00 atm of NO2(g) and no N2O4(g) at 100 C. After equilibrium is achieved, the pressure of NO2 is 1.56 atm.
