(a)
Interpretation:
When increasing the length of the box to 2 L for fixed total energy, the change in the number of accessible microstates and the entropy of the system should be explained.
Concept introduction:
Microstates is a specific microscopic configuration describing how the particles of a system are distributed among the available energy levels.
In a system, the entropy of a system depends on the total number of possible microscopic states by the Boltzmann relation as shown below:
Here,

Answer to Problem 1E
Number of microstates and the entropy increases.
Explanation of Solution
Given information:
Number of particles = 5
1D box length = L
When the length of the box is increased to 2 L, the number of the microstates increases for fixed total energy. the energy levels are shifted to lower values and are more closely spaced. Therefore,
more energy levels are accessible
According to the
(b)
Interpretation:
Whenthe total energy for constant box length is increased, the change in the number of accessible microstates and the entropy of the system should be explained.

Answer to Problem 1E
Number of microstates and the entropy increases.
Explanation of Solution
Given information:
Number of particles = 5
1D box length = L
With the increase of total energy, the number of microstates increases because more energy levels are accessible.

- For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.arrow_forwardHighlight the chirality (or stereogenic) center(s) in the given compound.
