Assertion `(A):` 1 Faraday of electricity deposits `1 g` equivalent of `Ag , Cu` or `Al`.
Reason `(R): 1 mole` of electrons are required to reduce `1 mol e of Ag^(o+)` or `(1)/(2) mol e of Cu^(2+)` or `(1)/(3) `mole of `Al^(3+)` ions.

Options

A. If both the assertion and reason are true but the reason is ont the correct explanation of assertion
B. If both the assertion and reason are true but the reason is not the correct explanation of assertion.
C. If the assertion is true but reason is false.
D. If assertion is false but reason is rue

Answer

b

Explanation

Both A and R are correct. But R is independent of A
i.e not the explanation of A .
`1 F = 1 Eq` of any compound
i.e.
`1 F=1 Eq` of `Ag^(o+) =Eq` of `Cu^(2+) =1` Eq of `Al^(3)`
` 1 mol of `Ag^(o+) =1/2` mol of `Cu^(2+)`
` 1/3` mole of `Al^(3+)`.
