Question- Calculate the E (degree) for each of the following reactions and indicate (Y/N) if it occurs spontaneously or is not spontaneous-
Part A) 2 MnO4- (aq) + 5 Hg2^2+ (aq) + 16 H+(aq) yields 2 Mn^2+(aq) + 10 Hg ^2+ (aq) + 8 H2O(I)
Part B) NiCl2(aq) + Pb(s) yields PbCl2(aq) + Ni(s)
Please define why you think that's the right answer
