For a given reaction:
`A^(x+n) + n e rarr A^(x+)`,
The `E_(RP)^(@)` is known along with concentration of `A^(x+n)` and `A^(x+)` ions. Select the correct statement:

Options

A. The value of `n` can be evaluated
B. The value of `x` can be evaluated
C. The value of `(x+n)` can be evaluated
D. The value of `n, x` and `(x+n)` can be evaluated

Answer

A

Explanation

`E_(OP) = E_(OP)^(@) - (0.059)/(n)"log"([A^((x+n)+)])/([A^(n+)])`
