Solution

The correct option is B 1
$2$ moles of $N O$ reacts with $1$ mole of $O_{2}$ to produce $2$ moles of $N O_{2}$ .

Hence, $1$ mole of $N O$ will react with $0.5$ moles of $O_{2}$ to produce $1$ mole of $N O_{2}$ .

Hence, the correct option is $(B)$ .

If 1.0 mol of NO is mixed with 1.0 mol of O2 as given in the following reaction then the number of moles of NO2 produced is___________.2NO(g)+O2(g)→2NO2(g)

The correct option is B 12 moles of NO reacts with 1 mole of O2 to produce 2 moles of NO2.Hence, 1 mole of NO will react with 0.5 moles of O2 to produce 1 mole of NO2.Hence, the correct option is (B).
