chapter 5 limiting reactants and percent yield?

2 NO + O2 --> 2 NO2
Since all of the NO has been consumed and since you still have some O2 remaining, NO is the limiting reactant in the diagram.

Limiting reactant .....
2NO(g) + O2(g) --> 2NO2(g)
...6............6 .............. 0 .................. before
...0............3 .............. 6 .................. after
NO is the limiting reactant. There is an excess of O2. The yield is 6 molecules of NO2, which is proportional to the 6 molecules of NO. The balanced equation indicates that 1 molecule of O2 will react with 2 molecules of NO, and that 3 molecules of O2 will react with 6 molecules of NO. It's the same ratio.
6 molecules NO.... 2 molecules NO
---------------------- = ----------------------
3 molecules O2..... 1 molecule O2
