We see that in the second law of thermodynamics, for any spontaneous process, the entropy of the universe will increase. With a very generalized approach, please try to explain how one spontaneous chemical reaction may increase entropy through its interactions with the environment.

Answer #1

Ans:-

Second law of thermodynamics:

the state of entropy of the entire universe, as an isolated system, will always increase overtime.

Changes in the entropy in the universe can never be negative entropy:

Entropy of a system as a measure of amount of disorder in the system.

for spontaneous process the entropy of the universe will increase.

Ex:

Solids have a much more regular structure than liquids.

Liquids are therefore more disorded than solids.

gases are more disordered than liquids.

gases are more disordered than liquids, so the entropy of the system increases.

The second law of thermodynamics says that the total amount of entropy, or randomness, in the universe cannot decrease. However, we see all around us objects that become more ordered-for example, the development of a biological organism or water that freezes. The decrease in entropy, or randomness, in such cases does not violate the second law because Group of answer choices: - there is always a greater increase in entropy somewhere else. - energy must be added. - energy must...

***Physical Chemistry Question***** The concept of entropy, and the second law of thermodynamics have often been used (usually misused in reality) to “explain” all kinds of things. It is frequently up to chemists to set the record straight in such cases. One argument which has been used to “disprove” evolution goes something like this: Living beings are more complex than nonliving systems. Furthermore, humans are more biologically complex than lower life forms such as monkeys. Entropy is a measure of...

For any system that may undergo any process, we expect the process to occur spontaneously only if ∆Guniverse<0. For a chemical system that may react,∆G sys=RTln(Q/K), so under standard state conditions (where [X]º=1 M and Px=1 atm) ∆Gsys=∆G°= RTln(1/K)= –RTlnK. Thus, at equilibrium (whereQ=K), ∆G= RTln(1) = 0. Use these ideas to explain why the laws of thermodynamics predict that no chemical reaction in a closed system should ever go to 100% completion.

Q: Summarize below article in 5 to 7 lines. (Long Term interest rate) Managing Risks Associated with the Future Course of Long-Term Interest Rates- As I noted when I began my remarks, one reason to focus on the timing and pace of a possible increase in long-term rates is that these outcomes may have implications for financial stability. Commentators have raised two broad concerns surrounding the outlook for long-term rates. To oversimplify, the first risk is that rates will remain...
