an airbus 350 passed right over my house yesterday coming into Miami from London. the flight time for this flight is 9 hr 50 minutes. This aircraft burns about 5400 kg/hr and the density of jet fuel is 775.g /Liter. If 3.785 = 1.00 gals calculate how many gallons of fuel this a350 consumed on the flight

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.
