In which of the following substances will electrolysis NOT occur when an electrical
current is passed through it?
(A)
(B)
Dilute sulfuric acid
Solid sodium chloride
Molten sodium chloride
Sodium hydroxide solution

the objects have the same charge.

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.
