In 1909 Fritz Haber discovered the workable conditions under which nitrogen, N2(g), and hydrogen, H2(g), would combine to
produce ammonia. The conditions included medium temperature (-500°C), very high pressure (-351kPa), and an iron catalyst.
The reaction is represented by the equation:
N2(g) + 3H2(g) - 2NH3(g)

B. 1.21 mol N2

C. 1.67 mol N2

D. 2.40 mol N2
