Haber’s process of manufacture of ammonia uses Fe as a catalyst. When Nitrogen is adsorbed on the surface of iron, an electron transfer occurs from the metal surface to N2. The CORRECT statement(s) among the following regarding this adsorption is/are

The electron from metal will be transferred to the LUMO, i.e., one of the π2p* MOs. This in turn results in lowering of bond order and hence lengthening of the bond.As there is realignment of electrons during this process, it is chemisorption. Adsorption is always exothermic.
