[Alyssa Bryan 3F]

For each reaction that is spontaneous under standard conditions (K>1), write a cell diagram, determine the standard cell potential, and calculate deltaG for the reaction:
for part b) 2Hg^2+(aq) + 2Br-(aq) = Hg2^2+(aq) + Br2(l)
How do you determine that this reaction is not spontaneous?

[KHuang1L]

You would have to identify the half reactions and then use the standard E value of the half reactions to calculate the standard E cell value. If the E cell value is positive, then the reaction is spontaneous. If the E cell value is negative, then the reaction is not spontaneous.
