Yeast can spontaneously ferment the sugar in grapes or apples and form
ethanol. When the process occurs in grapes, it results in wine. In apples, it
produces a beverage called hard cider. The first stage in the fermentation
process is exothermic, and the balanced equation for the reaction is as
follows:
CH,20,(aq)---2C, H,OH(aq) + 200,
Determine whether entropy increases in this reaction and relate the
change in heat energy and entropy the spontaneity of the process.
