N2+3H2->2NH3
What volume of hydrogen is necessary to react with five liters of nitrogen to produce ammonia? (assume constant temp. and pressure.)

  • Chem-Gas Stoichiometry - ,

    There is a long way and a short way. The long way uses conventional stoichiometry. The short way says that for an all gaseous reaction, we can omit changing everything to mols, making conversions, and changing back to liters. We can just operate in liters. Therefore, 1 liter of N2 will require 3 liters of H2 to produce 2 liters of NH3. So 5 liters of N2*(xx/yy) = zz liters H2.
