Question

Li3N(s) + 2 H2(g) <-> LiNH2(s) + 2 LiH(s) dH° = -192 kJ/mol_rxn

Because pure H2 is a hazardous substance, safer and more cost effective techniques to store it as a solid for shipping purposes have been developed. One such method is the reaction represented above, which occurs at 200°C.

Which of the following happens to H atoms in the forward reaction?

A.

H atoms are oxidized only.

B.

H atoms are reduced only.

C.

H atoms are both oxidized and reduced.

✓ Correct
D.

H atoms are neither oxidized nor reduced.
