How many grams of H2 are needed to produce 45.41 grams of NH3? (MM of NH3 is 17.04 g/mol and MM of Hy is 2.02 g/mol)

a electronegativity decreases beacuse the size of nucleus is bigger.

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.
