22. The equilibrium constant for the reaction H2(g) + 12(g) 2HI(g) is 54.6. The concentration of HI in the tube at equilibrium was found to be 0.0706 moles/liter. What is the equilibrium concentration of H2? Assume hydrogen and iodine had same initial concentrations A) 4.78 x 10-3 M B) 9.55Ã10-3 M C) 2.34Ã10-3 M D) 1.17 x 10-3 M 23. Given the following reaction: CO (g) + 2H2 (g) CH3OH (g) 0.42 mol of CO and 0.42 mol of H2 were placed in a 1.00L reaction vessel. At equilibrium, there were 0.29 mol of CO. What is the equilibrium constant Kc at this temperature? A) 2.80 B) 0.357 C) 14.5 D) 17.5 24 2502 (g) + O2 (g) 2503 (g) The initial concentrations of the reactants were 0.060 molVL of SO2 and 0.050 mol/L of O2. After equilibrium is reached, the concentration of SO3 is 0.040 mol/L. What is the equilibrium concentration of O2? A) 0.010 MM B) 0.020 M C) 0.030 M D) 0.040 MM
