If the volume of a sample of oxygen is 0.200L when the pressure is 3.000 atm and the temperature is 37.0 C. Then what is the new temperature if the volume increases to 0.400 L and the pressure decreases to 2.000 atm?

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 concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
