Question

The questions consist of two atatements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses :
Assertion : If standard reduction potential for the reaction `Ag^+ + e^(-) -> Ag` is `0. 80 ` volt, then for the reaction `2Ag^+ +2e^(-) ->2Ag`, it will be `1, 60` volt .
Reason : If concentration of `Ag^+` ions is doubled , the standard electrode potential is also doubled.
A. If both assertion and reason are correct and reason is correct explanation for assertion.
B. If both assertion and reason are correct but reason is not correct explanation for assertion.
C. If assertion is correct but reason is incorrect.
D. If assertion and reason both are incorrect.

Answer 1

Correct Answer - D
(d) Correct assertion : If standard reduction potential for the reaction, `Ag^(+)+e^(-) to Ag` is 0.80 volt, then for the reaction `2Ag^(+)+2e^(-) to 2Ag` is also +0.80 volt.
Correct reason : The effect of `E^(@)` value for an electrode cannot change.
