According to the balanced equation, 1 mole of NH3 reacts with 1 mole of Cl2 to form 1 mole of N2 and 3 moles of HCl. Therefore, the limiting reactant is NH3 as there are equal volumes of NH3 and Cl2. The reaction will use up all 15.0 L of NH3 and form 15.0 L of N2 and 45.0 L of HCl (3 times the volume of NH3 used). After the reaction, there will be no NH3 or Cl2 left, but there will be excess N2 gas (15.0 L initially formed) and 30.0 L of HCl (45.0 L initially formed, minus the 15.0 L used to react with NH3). Therefore, the volume of each gas is: N2 = 15.0 L, Cl2 = 0.00 L, N2H4 = 5.00 L, and HCl = 30.0 L, which corresponds to choice B.
