Two nonpolar organic liquids, hexane (C 6 H 14 ) and heptane (C 7 H 16 ),

Question:

Two nonpolar organic liquids, hexane (C6H14) and heptane (C7H16), are mixed.

(a) Do you expect ΔHsoln to be a large positive number, a large negative number, or close to zero? Explain.

(b) Hexane and heptane are miscible with each other in all proportions. In making a solution of them, is the entropy of the system increased, decreased, or close to zero, compared to the separate pure liquids?
