A supersaturated solution of sucrose (C12H22O11) is madeby dissolving sucrose in hot water and slowly letting thesolution cool to room temperature. After a long time, theexcess sucrose crystallizes out of the solution. Indicatewhether each of the following statements is true or false:(a) After the excess sucrose has crystallized out, the remainingsolution is saturated.(b) After the excess sucrose has crystallized out, the systemis now unstable and is not in equilibrium.(c) After the excess sucrose has crystallized out, the rate ofsucrose molecules leaving the surface of the crystals tobe hydrated by water is equal to the rate of sucrose moleculesin water attaching to the surface of the crystals.
