the group of elements called the noble gases typically do not chemically react with other elements. this is true because noble gases tend to have A- more protons b- fewer neutrons than other electrons c- full outer shell of valence electrons d- a single valence electron in the outer shell​

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.
