JEE Main levelSingle correct optionDifficulty 2 of 3df029

In a three-way catalytic converter (Pt-Rh), the reaction $2 NO + 2 CO N X_{2} + 2 CO X_{2}$ occurs. When $6$ mol of NO is completely converted with excess CO, the total moles of gaseous products formed is

For 2 NO the products are 1

N X_{2}

and 2

CO X_{2}

(balanced: N 2, O 4, C 2). For 6 mol NO this gives 3 mol

N X_{2}

and 6 mol

CO X_{2}

, total 9 mol.
