Question
Assertion: ECell should have a positive value for the cell to function.
Reason: `"E"_("cathode") < "E"_("anode")`
Options
Both assertion and reason are true and the reason is the correct explanation of assertion.
Both assertion and reason are true and the reason is not the correct explanation of assertion.
Assertion is true but the reason is false.
Both assertion and reason are false.
Assertion is false but reason is true.
Solution
Assertion is true but the reason is false.
Explanation:
ΔG- = - `"nFE"_"cell"^-`
When the value of `"E"_"cell"^0` is positive then ΔG− becomes negative. Hence the reaction becomes possible.
