At 1285oC the equilibrium constant for the reaction Br2(g) ⇌ 2Br(g) is Kc =0.104. A 0.200 L vessel containing an equilibrium mixture of the gases has 0.29 g Br2 (g) in it. What is the mass of Br(g) in grams in the vessel? Molar mass of Br = 80 g/mol. Keep 3 digits after decimal point.

level 4 to level 2 : ))

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.
