A) 3 : 1
B) 2 : 1
C) 1 : 1
D) 3 : 2
Correct Answer: D
Solution :
Not Available [d] At cathodes : \[F{{e}^{+}}+2{{e}^{-}}\xrightarrow[{}]{}Fe;\] \[F{{e}^{3+}}+3{{e}^{-}}\xrightarrow[{}]{}Fe\] \[{{({{E}_{Fe}})}_{1}}=\frac{At.\,\,wt.}{2};\] \[{{({{E}_{Fe}})}_{2}}=\frac{At.\,\,wt.}{3}\] Hence,\[\frac{{{({{E}_{Fe}})}_{1}}}{{{({{E}_{Fe}})}_{2}}}=\frac{3}{2}\]You need to login to perform this action.
