Balance the following chemical reaction and tell what type it is. Explain why you chose that type of reaction in your answer.
AlPO4 + CaF2 → AlF3 + Ca3(PO4)2

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.
