according to the reaction
2KMnO4 + H2SO4 +5SO2 = K2SO4 + MnSO4 + 5S03
(BALANCE ONLY THE REQUIRED PART)
2 . 158 g of KMnO4 = 320 g og S02
therefore 15.8 g of KMnO4 = 16 g of S02
now see the reaction
4Fes2 + 5o2 = 8SO2 + 2FeO3
from the reaction
512 g of SO2 = 480 g of FeS2
therefore 16 g of SO2 = 15 g of FeS2
rate if correct or useful
