A hypothetical electrochemical cell is show below A | A ⁺(x M ) | B ⁺(y M ) | B The emf measured is +0.20 ~V . The cell reaction is:
Options
- AA + B ⁺ A ⁺+ B
- BA ⁺+ B A + B ⁺
- CA ⁺+e⁻ A ; B ⁺+e⁻ B
- Dthe cell reaction cannot be predicted
Correct answer
A. A + B ⁺ A ⁺+ B
Step-by-step solution
A / A ⁺(x M ) | B ⁺(y M ) / B E _ cell =+0.20 ~V G =-v e Therefore given cell reaction is spontaneous At Anode A A ⁺+e⁻ array ll At Cathode & B ⁺+e⁻ B Cell reaction & A + B ⁺ A ⁺+ B array
