3.00 L of NO(g) at 1.20 atm and 25°C is reacted with 1.60 L of H2(g) at 2.00 atm and 25°C according to the
following balanced equation.
2NO(g) + 2H2(g) N2(g) + 2H20(g)
What is the limiting reactant, and how many moles of N2 gas will be produced?
NO is limiting; 0.0736 moles of N2 will be produced
O NO is limiting: O.147 moles of N2 will be produced
H2 is limiting; 0.131 moles of N2 will be produced
O Hz is limiting: 0.0654 moles of N2 will be produced
