Calculate the n-factor of reactants in the given reactions.
(b) `FeC_(2)O_(4)rarr Fe^(3+)+CO_(2)`

Text Solution

Verified by Experts

`Fe^(+2)rarrFe^(+3)+e^(-) and Cr_(2)O_(4)^(2-) rarr 2Cr^(+6)rarr 2Cr^(+6)+6e^(-)`. This means `FeCr_(2)O_(4)rarr Fe^(+3)+2Cr^(+3)+2Cr(+6)+7e^(-)`.
`"E.Mass"_(FeCr_(2)O_(4))=("M.Mass")/(7)`
