How much faster does the hydrogen diffuse than the nitrogen?

How much energy is release when 51.0kg of hydrogen gas reacts in excess nitrogen gas?[More detail in Question]?

• Ammonia is produced commercially by the direct reaction of the elements. The formation of 1.00 moles of gaseous NH3 by this reaction releases 46.17 kJ of heat. How much energy (in kJ) is released, when 51.0 kg of hydrogen gas, H2, reacts in excess nitrogen gas, N2? How much energy is release when 51.0 kg of hydrogen gas reacts in excess nitrogen gas?

• Answer:

  The balanced equation is N2 + 3 H2 = 2 NH3 moles H2 = 51000 g/ 2.016 g/mol=2.53 x 10^4 the ratio between H2 and NH3 is 3 : 2 moles NH3 formed = 2.53 x 10^4 x 2/3 =1.69 x 10^4 energy released = 46.17 kJ x 1.69 x 10^4 mol/ 1.00 mol=7.80 x 10^5 kJ
