A gas mixture contains each of the following gases at the indicated partial pressure. CO2 = 345 mmHg, Ar = 126 mmHg, O2 = 228 mmHg N2 = 168 mmHg, What is the total pressure of the mixture in mmHg?

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.
