Homework Answers
a) when attraction between molecules increases, entropy decreases as the randomness of molecules decrease.
b) when repulsion is there, the entropy increases due to the increased randomness between molecules.
Hence, we need to consider the relationship between entropy and Gibbs free energy .

Without doing any detailed calculation, specify for each process whether each of the following quantities is positive, negative or equal to zero: q, w, ∆U, ∆S, ∆Ssurr. Provide a brief explanation for each of your choices. If the question does not allow you to come to a definite conclusion, briefly discuss the possibilities.

Please provide correct answer for part B.
A manager is trying to decide whether to buy one machine or two.
If only one is purchased and demand proves to be excessive, the
second machine can be purchased later. Some sales will be lost,
however, because the lead time for producing this type of machine
is six months. In addition, the cost per machine will be lower if
both are purchased at the same time.
The probability of low demand is...
