Question #d4b5d

Answer 1

Well I don't what's exactly the question

Explanation:

First a galvanic cell is a type of electrochemical cell in which the redox reaction occurs spontaneously, that means the potential difference (`DeltaV_c`) of the cell is positive.
So what it says in the link in simpler words is: if you apply a `DeltaV` equal to `DeltaV_c` but opposite then the resulting `DeltaV` is 0 and the reaction won't occur. If you don't apply nothing then the reaction continues spontaneous. And if you a `DeltaV` greater and opposite to `DeltaV_c` then the reaction occurs in the reverse way.
