The cell potential of an electrochemical cell is positive. What does that tell you about the redox reaction?A.The reduction part of the reaction occurs at the anode.B.The oxidation part of the reaction occurs at the cathode.C.The reaction is spontaneous.D.The reaction is nonspontaneous.
Question
The cell potential of an electrochemical cell is positive. What does that tell you about the redox reaction?A.The reduction part of the reaction occurs at the anode.B.The oxidation part of the reaction occurs at the cathode.C.The reaction is spontaneous.D.The reaction is nonspontaneous.
Solution
The positive cell potential of an electrochemical cell indicates that the reaction is spontaneous. So, the correct answer is C. The reaction is spontaneous.
Here's why:
In an electrochemical cell, a positive cell potential means that the reaction is energetically favorable and will occur without the need for an external energy source. This is the definition of a spontaneous reaction.
As for the other options:
A. The reduction part of the reaction always occurs at the cathode, not the anode.
B. The oxidation part of the reaction always occurs at the anode, not the cathode.
D. A positive cell potential indicates a spontaneous reaction, not a nonspontaneous one.
