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?
