Asample of water in a sealed flask at 298 k is in equilibrium with its vapor. this is an example of a. chemical equilibrium b. phase equilibrium c. solution equilibrium d. static equilibrium

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.
