Question

What does a positive cell voltage mean?

1) the reaction will never occur.
2) the reaction requires added energy.
3) the reaction is spontaneous.
4) the reaction is nonspontaneous.

Answer 1

3) the reaction is spontaneous.

Step-by-step explanation:

Answer 2

A positive cell voltage indicates a spontaneous reaction that will occur without added energy.

Step-by-step explanation:

A positive cell voltage indicates that the reaction will occur spontaneously as written. In other words, it is a spontaneous reaction. This means that the reaction will happen on its own without the need for added energy.

For example, in a voltaic cell, if the anode is negative and the cathode is positive, a positive cell voltage would mean that the reaction is spontaneous, and electrons will flow from the anode to the cathode.
