17.4 mL of unknown H2SO4 solution was titrated by 0.20 M of NaOH. 41.51 mL of that NaOH solution was consumed to exactly completely neutralize the acid. What is the original molarity (in M) of the unknown H2SO4 solution?

the volume increases

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.
