Assertion : If standard reduction potential for the reaction Ag^ + +e^ - arrow Ag is 0.80 volt, then for the reaction 2 Ag^ + +2 e^ - arrow 2 Ag , it will be 1.60 volt. Reason: If concentration of Ag^ + ions is doubled

Correct answer: D. If both assertion and reason are false. Standard reduction potential of an electrode has a fixed value.

Assertion : If standard reduction potential for the reaction

\mathrm{Ag}^{+}+e^{-} \rightarrow \mathrm{Ag}

is 0.80 volt, then for the reaction

2 \mathrm{Ag}^{+}+2 e^{-} \rightarrow 2 \mathrm{Ag}

, it will be 1.60 volt. Reason: If concentration of

\mathrm{Ag}^{+}

ions is doubled, the standard electrode potential is also doubled.

AIf both assertion and reason are true and reason is the correct explanation of assertion.
BIf both assertion and reason are true but reason is not the correct explanation of assertion.
CIf assertion is true but reason is false.
DIf both assertion and reason are false.

D. If both assertion and reason are false.

Standard reduction potential of an electrode has a fixed value.
