Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2(g) + 2h2o(g) → 4hcl(g) + o2(g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound pressure at equilibrium cl2 34.7atm h2o 33.5atm hcl 12.3atm o2 94.9atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant digits.

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.
