Hydrogen, a potential future fuel, can be produced from carbon (from coal) and steam by this reaction:
Use average bond energies to calculate rxn for the reaction.
Solution:Step-1(a)The total number of electrons in P is 30. As P is similar to that of N , because as like N atom 2 2 2p also have five electrons in its valence shell [Ne] 3s 3p . Thus the valence atomic orbitals ofP2re 3s, 3p , 3pxnd 3py zThe MO electronic configuration of P is, 2 2 2 2 2 2 2 2 2 2 2 2 2 2 1s *1s 2s *2s 2px 2py 2pz *2px *2py *2pz 3s *3s 3p x 2 2 3p y . zStep-2The given figure shows formation of double bond by the overlapping of 3p orbital of P . 2Step-3Two electrons are present in the given MO of P molecule. 2 Step-4From the MO electronic configuration, it has been found that all the electrons are paired , thus itis diamagnetic in nature.
