Homework Answers
Because any noequilibrium state undergoes isothermal structural relaxation in time towards the supercooled liquid.
The entropy of the system falls out of constrained equilibrium, but the structures in the supercooled liquid are no yet frozen.

"Explain Vmax and Km in terms of your data (use correct units) If you data does not support the standard conclusion, can you ascertain why not? If you data is not suitable to draw a conclusion then you will need to get usable data. But you have to list where you got the data from and explain both sets." I understand you might not be able to answer this question without my data but can you walk me through how...

Rabbit farming is a perfectly competitive industry and all rabbit farms have the same cost curves. When the market price is $31 a rabbit, each farm maximizes profit by producing 1,000 rabbits a week. At this output, average total cost is $30 and average variable cost is $18 a rabbit. Minimum average variable cost is $14 a rabbit. Two points on the rabbit farm's supply curve are 1,000...
