Using a balanced chemical reaction and a periodic table, which of the following is not possible to calculate?
a. the molar mass of the products
b. the number of atoms in the reaction
c. the number of molecules in the reaction
d. the amount heat produced in the reaction

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
