Astudent thinks that the more protons an atom has, the more reactive it will be. which will best disprove this student's idea?

compare the reactivities of lithium (li) and krypton (kr).
note that rubidium has 48 neutrons.
compare the number of protons in cesium (ce) and xenon (xe).
count the number of neutrons in an atom of helium.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
