A hypothetical electrochemical cell is shown 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 predicated
Correct answer
A. A + B + → A + + B
Step-by-step solution
From the given expression At anode: A → A + + e At cathode: B + + e → B Overall reaction is: A + B + → A + + B
