Which of the following reactions of hydrogen with non - metals represents Haber's process ?

Options

A. `2H_(2) + O_(2) overset("heat")rarr 2H_(2) O, Delta H = -285.9 "kj mol"^(-1)`
B. `3H_(2)+N_(2)overset(673 K, Fe)underset(200 atm)rarr 2NH_(3), Delta H=-92.6 "kJ mol"^(-1)`
C. `H_(2) + Cl_(2) overset(hv)rarr 2HCI`
D. `2H_(2) + C overset(1100^(@)C)rarr CH_(4)`

Answer

B

Explanation

Formation of `NH_(3)` by reaction of hydrogen and nitrogen is known as Haber's process.
