At a certain temperature the reaction        CO2(g) + H2(g) CO(g) + H2O(g)2 has Kc = 2.50. If 2.00 mol of carbon dioxide and 1.5 mol of hydrogen are placed in a 5.00 L vessel and equilibrium is established, what will be the concentration of carbon monoxide? 

H2SO3(aq) HSO3(aq) + H+(aq)     Kc = 1.4 × 10–2 H2SO3(aq) SO32–(aq) + 2H+(aq)    Kc = 9.1 × 10–10 Given the above equilibrium constant data at 25°C, what is the value of Kc at this temperature for the reaction  HSO3–(aq) SO32–(aq) + H+(aq)?
