Calculate the E° for each of the following reaction. Decide whether each is product-favored in the direction written

2 Cl-(aq) + Cu2+(aq) --> Cu(s) + Cl2(g)

i got -1.020 but its wrong and i do not know why.

    If you will show the numbers you looked up and how you worked the problem I may be able to find the error. I looked the numbers up in an old old book of mine and found -1.02 v and the reaction is favored toward the reactants (not the products). I suspect the problem, and apparently you are keying the numbers into a computer database, is the last zero. The correct answer may be -1.02 and NOT -1.020 but I can't be certain of that without seeing your solution. What I'm saying is that I think you have included too many significant figures.
