Question

A variable, the opposite external potential ( E ext ) is applied to the cell Z n | Z n 2 + 1 M &#8741; C u 2 + 1 M | C u , of potential 1 . 1 V . When E e x t &#60; 1.1 V and E e x t &#62; 1.1 V , respectively electrons flow from

Quantrex Academy · Accepted Answer

Correct answer: B. anode to cathode and cathode to anode.

For a Daniel cell, E c e l l = 0.34 - ( - 0.76 ) = 1.10 &#160; V . When E e x t &#60; 1.10 &#160; V , electrons flow from anode to cathode in the external circuit. When E e x t &#62; 1.10 &#160; V , electrons flow from cathode to anode in the external circuit (reverse reaction).
