Below is an energy diagram for the decomposition of ammonia. The change in enthalpy of the reaction is +92.4 kJ/mol. Tell me if this is an
exothermic or endothermic reaction and explain what evidence you have
for that claim

i believe it is c.) 1575 j.

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.
