If 40.0 grams of magnesium is reacted with an excess of nitric acid, HNO3, how many grams of hydrogen gas will be produced?

the answer is c i took the test

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.

is it d? cause im still confusion
