Packet 7: Bonus 1
The Gibbs paradox is an apparent increase in entropy when ideal gases are subject to this process, which is resolved by treating particles as indistinguishable. For 10 points each:
[10m] Name this process that is accomplished using an impeller in reactors known as CSTRs. Devices that perform this process magnetically often double as hot plates.
ANSWER: mixing [or stirring; accept mixers or stirrers]
[10e] Stirring increases the rate of this process for soluble materials. This process, in which one material disperses through another, occurs up to the saturation point.
ANSWER: dissolution [or word forms like dissolving]
[10h] Stirring prevents solute from “oiling out” during this technique, which precipitates a pure substance from a supersaturated solution. Vacuum filtration is often used to dry the result of this technique.
ANSWER: recrystallization
