Can some help, it would help if I had answers for 8.5 and more practice 8.5

the solar system used to have much dust particles option no d

the answer is d. 74.02

wher is the rest of the question

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.
