determine which of the following pairs of reactants will result in a spontaneous reaction at 25 degrees celcius

a.Pb2+(aq) + Cu(s)

b. Ag+(aq) + Br- (aq)

c. Li+ (aq) + Cr(s)

d.Fe3+(aq) + Cd(s)

e. none of the above

I understand how to find the values in the tables, and to solve from there, but for the ones such as Pb2+ I dont understand where those values come from, they arent in the table, can anyone help?
