Which of the following statements is/are correct about the followig reaction? `Fe_(3)O_(4)overset(Delta)toFe_(2)O_(3)`.A. The equivalent weight of `Fe_(3)O_(4)` is `M_(1)(M_(1)=` molecular weight of `Fe_(2)O_(4))`B. The equivalent weight of `Fe_(3)O_(4)` is `(M_(1))/(3)`.C. The equivalent weight of `Fe_(2)O_(3)` is `(3M_(2))/(2)(M_(2)=` molecular weight of `Fe_(2)O_(3))`.D. The equivalent weight of `Fe_(2)O_(3)` is `(M_(2))/(2)`.

Answer» Correct Answer - A::C
`{:(Fe_(3)O_(4),Fe_(2)O_(3)),(3x-8=0(3x=8),2x-6=0 (2x=6)),(x=(8)/(3),x=3):}`
`_(2)(Fe^((8)/(3)+))_(3)to3(Fe^(3+))_(2)+2e^(-)`
`{:[(x=(8)/(3)xx2xx3),(x=16),("n-factor"=(2)/(2)=1),(Ew_(1)=(M_(1))/(1))]:}`
`{:[(x=18),(3mol=2e^(-)),(1mol=(2)/(3)e^(-)),("n-factor"=(3)/(2)),(Ew_(2)=(M_(2))/((2)/(3))=(3M_(2))/(2)):}]`
