Answer

See explanation below.

Work Step by Step

1 A long hydrocarbon chain can rotate and vibrate in more ways than a short one, so entropy increases with chain length. Hence CH3OH(l) has lower molar entropy than C2H5OH(l) 2 KClO3(s) has lower molar entropy than KClO3(aq) because KCLO3 in aqueous phase has more freedom of movement 3 Na(s) has lower entropy than K(s) because with heavier atom in same periodic group has more entropy
