Solution

The correct option is A $N O (g)$
$2$ moles of $N O$ require $1$ mole of oxygen from the above-balanced reaction.
Here, we have $1$ mole of $N O$ and $1$ mole of oxygen.
So, the limiting reagent is $N O$ .
Hence, the correct option is $(A)$

If 1.0 mol of NO is mixed with 1.0 mol of O2 as given in the following reaction, then the limiting reagent is______.2NO(g)+O2(g)→2NO2(g)

The correct option is A NO(g)2 moles of NO require 1 mole of oxygen from the above-balanced reaction.Here, we have 1 mole of NO and 1 mole of oxygen.So, the limiting reagent is NO.Hence, the correct option is (A)
