When O2 is adsorbed on a metallic surface, electron transfer occurs from the metal to O2. The TRUE statement(s) regarding this adsorption is(are) (A) O2 is physisorbed (B) heat is released (C) occupancy of π*2p of O2 is increased (D) bond length of O2 is increased |

Answer» (B) heat is released (C) occupancy of π*2p of O2 is increased (D) bond length of O2 is increased * Adsorption of O2 on metal surface is exothermic. * During electron transfer from metal to O2 electron occupies π* 2p orbital of O2. * Due to electron transfer to O2 the bond order of O2 decreases hence bond length increases. |
