In viewof thesigns ofDelta _r G^(@)forthefollowingreactions:PbO_2+Pb to2 PbO, Delta_ rG^(@) lt0SnO_ 2+Snto2 SnO,Delta_ r G^(@) gt0 whichoxidation states are morecharacteristicforleadandtin ?

Answer»

Forlead` +4`, fortin + 2
Forlead+2, for tin+ 2
Forlead+4, fortin+4
Forlead +2, for in+4

Solution :Since`DELTA _rG^(@) `is- veforfirstreaction,THEREFORE, +2oxidationstate of Pb is morestable. Further since` Delta _r G^(@) ` is+ ve for SECONDREACTION,therefore,+4oxidationstateof SN is morestable. Thus, option (d) iscorrect.
