Question

For a galvanic cell where the standard free energy change is negative and the cell potential is positive, the reaction in the cell must be: Select the correct answer below:

a. always spontaneous
b. never spontaneous
c. spontaneous at certain temperatures
d. impossible to predict

Answer 1

The reaction in a galvanic cell with a negative standard free energy change and positive cell potential is always spontaneous. Correct option is a.

Step-by-step explanation:

The presence of a positive cell potential indicates that the reaction in a galvanic cell is spontaneous. Therefore, the correct answer is option a, always spontaneous.
