<span>Best Answer: Mn(ii) is catalyst
Stetep-1 is slow step
Steps-2,3 are fast steps
intermediates are Mn(iii)and Mn(iv)
since step -1 is slow rate depends on Ce(iv) and Mn(ii) only
not on Tl(i) as it is involved in fast step-3</span>
AsH3 has five valence electrons, so the molecule will have 3 bonding domains and one non-bonding domain (lone pair) around the central atom. The geometry is trigonal pyramidal, and the angles are around 107 degrees.
AsH3 and hydrogen are very close in electrongativity, so there really is no partial charges. There may be a slight electron pull towards hydrogen, but it would be nearly insignificant

Mendeleev's greatest contribution to science is certainly the Periodic Table of Elements, which says the properties of basic elements repeat periodically when they are arranged by their atomic number. He made the discovery in 1869 during his work on the award-winning textbook on chemistry basics.
