Iodine, I2, is a blue-black solid, but it easily vaporizes to give a violet vapor. At high temperatures, this molecular substance dissociates to atoms:

An absent-minded professor measured equilibrium constants for this dissociation at two temperatures, 700oC and 800oC. He obtained the Kp values 0.01106 and 0.001745, but he couldn€™t remember which value went with what temperature. Can you please help him assign temperatures to the equilibrium constants? State your argument carefully.
