The difference between Δ G o and Δ G should be explained and under what circumstance both the given parameters become equal has to be indicated. Concept introduction: Any natural process or a chemical reaction taking place in a laboratory can be classified into two categories, spontaneous or nonspontaneous. Spontaneous process occurs by itself, without the influence of external energy. In spontaneous process the free energy of the system decreases and entropy of the system increases. Nonspontaneous process requires an external influence for initiation. In nonspontaneous process the free energy of the system increases but entropy in the system decreases. In thermodynamics a process is spontaneous if it is taking place by itself without the help of external energy. All spontaneous process will have highly energetic initial state than the final state. This indicates that while the process occurs, there is a decrease in free energy of the system. The increase in randomness also favors the spontaneity of a process. In non-spontaneous process, there is a requirement of external energy source. The free energy of the system increases. The entropy decreases in non-spontaneous process.

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
Interpretation:
The difference between ΔGo and ΔG should be explained and under what circumstance both the given parameters become equal has to be indicated.
Concept introduction:
Any natural process or a chemical reaction taking place in a laboratory can be classified into two categories, spontaneous or nonspontaneous. Spontaneous process occurs by itself, without the influence of external energy. In spontaneous process the free energy of the system decreases and entropy of the system increases. Nonspontaneous process requires an external influence for initiation. In nonspontaneous process the free energy of the system increases but entropy in the system decreases.
In thermodynamics a process is spontaneous if it is taking place by itself without the help of external energy. All spontaneous process will have highly energetic initial state than the final state. This indicates that while the process occurs, there is a decrease in free energy of the system. The increase in randomness also favors the spontaneity of a process.
In non-spontaneous process, there is a requirement of external energy source. The free energy of the system increases. The entropy decreases in non-spontaneous process.
Problems
1.
Acids (11) and (12) were both made by Grignard
addition to CO2 rather than by cyanide displacement
(p T 80).
Why?
(11)
-CO2H
MeO-
(12)
CO,H
2.
Aldehyde (8) was needed for a butenolide synthesis.
How would (8) be made?
CHO
Show work with explanation needed. don't give Ai generated solution. don't copy the answer anywhere
