Expert Solution & Answer
Interpretation Introduction
Interpretation:
For the process A(l)→A(g), the favored direction due to change in energy probability, position probability and positional probability needs to be determined. To favor the process, whether the temperature of the system is raised or lowered needs to be determined.
Concept Introduction:
In an isothermal and isobaric (constant pressure and temperature) thermodynamic system, Gibbs free energy is a measure of the amount of energy available to do work.
Answer to Problem 1DQ
To favor the process as written the temperature of the system must be raised because the conversion of liquid to gas is an endothermic reaction.
Explanation of Solution
As molecules in gaseous state could move faster than the molecules in the liquid state thus, the gaseous molecules contain more kinetic energy and hence A(l)→A(g), direction is favored by energy randomness. The direction of liquid to gas is favored by positional randomness.
This is because the movement of the gaseous molecules is more random than liquid molecules of a substance.
To favor the process as written, the temperature of the system must be raised because the conversion of liquid to gas is an endothermic reaction.

Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in top
molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will
contribute to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in bottom
molecule
In the drawing area below, draw the major products of this organic reaction:
1. NaOH
?
2. CH3Br
If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area
instead.
No reaction.
