Assertion(A) `E_(Ag^(+)//Ag^(@)` increase with increase in concentration of `Ag^(+)` ions.
Reason(R) `E_(Ag^(+)//Ag)` has a positive value.

A

Both assertion and reason are true and the reason is the correct explanation of assertion.

B

Both assertion and reason are true and reason is not the correct explanation of assertion.

C

Assertion is true but the reason is false.

D

Both assertion and reason are false.

To solve the question regarding the assertion and reason related to the electrochemical behavior of silver ions, we will break it down step by step. ### Step 1: Understanding the Assertion The assertion states that the standard electrode potential \( E_{Ag^+//Ag} \) increases with an increase in the concentration of \( Ag^+ \) ions. ### Step 2: Nernst Equation To analyze this, we can use the Nernst equation, which is given by: \[ ...
