Carbon monoxide binds strongly to the Fe2+ion of the heme group of protein myoglobin. Suppose you have at your disposal a supply of myoglobin, a suitable buffer in which to suspend the protein,12C16O,13C16O,12C18O,13C18O,
Hydrogen is more electronegative and the shared electron pair is likely to be found closer to the hydrogen atom. Hydrogen is more electronegative and the shared electron pair is likely to be found closer to the chlorine atom.
This equation means that no matter how much carbon monoxide and oxygen gas is added to the flask, only 2 moles of CO and 1 mole of O2 will react to make two moles of Co2.
