# What is a plausible mechanism for the Haber process?

Jun 20, 2015

Do you mean the reaction that forms ammonia? If so, it is the Haber Process.

${N}_{2} + 3 {H}_{2} \iff 2 N {H}_{3}$

A plausible mechanism (that I just thought up, actually) for this is:

N≡N + H-H -> HN=NH

$H N = N H + H - H \to {H}_{2} N - N {H}_{2}$

${H}_{2} N - N {H}_{2} + H - H \to N {H}_{3} + N {H}_{3}$

where each step is a reduction step of nitrogen transferring electrons to grab both hydrogen in each step (one N single bond e- pair is donated to a hydrogen, and one e- pair from the hydrogens is donated to break the single bond and bond to the other, cationic nitrogen).

The accepted mechanism is here, though.
