In looking at these three diagrams, we can determine the molecules of co2 that can be produced from the stoichiometry of this balanced chemical reaction.
00:14
In the first diagram, there are three o2 molecules and three methanol molecules.
00:21
Because we need more oxygen than methanol, three oxygen molecules for every two methanol molecules with equal amounts of both, the oxygen ends up being the limiting reactant.
00:39
That means when the three molecules of oxygen react will produce just two molecules of carbon dioxide.
00:49
Then for b, we have one methanol molecule, and we have six oxygen molecules.
00:57
For every methanol molecule, well, for every two, we need three oxygen, so we've got plenty of oxygen.
01:04
So methanol is now our limiting reactant...
