I am not sure where your troubles are with these problems, so I can be of limited help here. I would say try another way of calculating delta s of the rxn....say the one where you sum the delta s's of products and subtract (?) the sum of the delta s's of the reactants. (I don't have the book with me but the equation is in there)If this doesn't help, let me know where your troubles lie and I will try again. Terri

I tried doing dS(products) - dS(reactants), with various versions of the problem even, and it kept saying I was wrong. It might want decimal points, but there aren't any in the values in the book, so I don't know how to get the right answer...

The dG in the book is given in kJ/mol, and the CALM answers ask you to give the answer in J/mol. This may possibly be the problem...it was for me...if you change your answer into Joules it may help.....Hope this is of use!
