Recall that the greater the E°cell of a redox reaction, the more likely the reaction will occur (more spontaneous reaction)
E°cell > 0 → spontaneous in the forward direction
E°cell < 0 → nonspontaneous in the forward direction
We will have to calculate for the cell potential to determine the spontaneity of the redox reaction using the following steps:
Is the following reaction likely to take place spontaneously?
c. Pb(s) + 2H2O(l) → H2(g) + 2OH−(aq) + Pb2+(aq)
