D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`2KMnO_(4)+3H_(2)SO_(4) to K_(2)SO_(4) +2MnSO_(4)+3H_(2)O +5[O]`
`([2FeSO_(4)+H_(2)SO_(4)+[O]toFe_(2)(SO_(4))_(3)+H_(2)O]xx5)/ul(2KMnO_(4)+10FeSO_(4)+8H_(2)SO_(4)to K_(2)SO_(4)+2KnSO_(4)+5Fe_(2)(SO_(4))_(3)+8H_(2)O)`
`2" mole" KMnO_(4)-=10 " mole" FeSO_(4)`
`1 "mole" KMnO_(4)-=5 " mole" FeSO_(4)`
