The limiting reagent is NO

explanation
writ e the balanced equation for reaction

2NO + O2 → 2NO2

from the equation above 2 moles of No reacted with 1 mole of O2 to form 2 moles of NO2

the mole ratio between No to NO2 is 1:1 therefore the moles of NO2 also 0.68 moles

the mole ratio between o2 to NO2 is 1:2 therefore the moles of NO2 = 1 x 0.79 = 1.58 moles, there O2 is in excess

this means NO is the limiting reagent
