You can make ester from a carboxylic acid as well as an alcohol or hydrolyze an ester to the corresponding alcohol as well as carboxylic acid under similar conditions however at identical temperatures. Does this negate the second law of thermodynamics? In which direction is the reaction spontaneous as well as what must you do to make the non-spontaneous reaction spontaneous, without changing the temperature?
