AIPMT PRELIMS 2006 Chemistry Electrochemical Cells MCQ Question
A hypothetical electrochemical cell is shown below AlA₊ (xM)∥ B₊ (yM)∥ B The emf measured is +0.20V. The cell reaction is:
A + B → A + B⁺
A + B⁺ → A + B
A⁺ + B → A + B⁺
A + B → A⁺ + B
Correct Answer
Detailed Explanation
The positive emf indicates that the reaction proceeds as written: A + B⁺ → A + B, where B⁺ is reduced.
