i think first one.
I- more stable than I2 ..
consider the following reaction
I:2Cu2++4I-→Cu2I2+I2
II:Fe3++SCN-→[FeSCN]2+
reversible nature can be expected in which of the reactions.
sky i dont have any answers for the question.
my doubt is ΔG=nFE. wat is n here.
i did'nt get ur question u want which of the reaction is reversible or you want to know the direction of spontaneity in above reactions
for the first part i have stated
every rxn is reversible in nature except nuclear reactions
