The two factors that determine whether a reaction is spontaneous are:

Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release.

A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. The entropy of the system increases during a combustion reaction. The combination of energy decrease and entropy increase dictates that combustion reactions are spontaneous reactions.

• Enthalpy: When the reaction gives off energy, then the reaction is said to be spontaneous.
• Entropy: It is the measure of randomness in a system. As the randomness of the reaction increases, the spontaneous is the reaction.

ii. Entropy (1 point) Entropy affects the spontaneity of a reaction because if there is an increase in entropy the reaction is more likely to be spontaneous, but if there is a decrease in entropy the reaction is more likely to be nonspontaneous. If ΔG is negative then the reaction is spontaneous.

In chemistry, a spontaneous processes is one that occurs without the addition of external energy. A spontaneous process may take place quickly or slowly, because spontaneity is not related to kinetics or reaction rate.

Definition of a Spontaneous Process A spontaneous process is one that occurs on its own, without any energy input from the outside. For example, a ball will roll down an incline; water will flow downhill; ice will melt into water; radioisotopes will decay; and iron will rust.

Spontaneous Reactions: Spontaneous reactions refer to the chemical reactions that occur without being driven by an outside force. Nonspontaneous Reactions: Nonspontaneous reactions refer to the chemical reactions that require an energy input to proceed.

Spontaneous processes are irreversible. Like total energy, E, and enthalpy, H, entropy is a state function. The second law of thermodynamics states that the entropy of the universe increases for spontaneous processes, and the entropy of the universe does not change for reversible processes.

Spontaneous processes are irreversible because they can be reversed only by taking a different path to get back to their original state. A reversible process can take the same path to return to its original state. An irreversible process must take a different path to get back to its original state.

ΔG<0 is always true for spontaneous process.

Is Gentrification a spontaneous and irreversible process? What you mean by “spontaneous” is: following the dynamics of market transactions, incentives, and private gain”. This is not spontaneous; but it is not a publicly regulated process (in most jurisdictions).

An irreversible process is a process that cannot return both the system and the surroundings to their original conditions. Four of the most common causes of irreversibility are friction, unrestrained expansion of a fluid, heat transfer through a finite temperature difference, and mixing of two different substances.

Gentrification is a highly contested issue, in part because of its stark visibility. Gentrification has the power to displace low-income families or, more often, prevent low-income families from moving into previously affordable neighborhoods.

By increasing the amount of neighborhood interaction between households of varying socioeconomic status, gentrification might lead to long-term improvements in the living standards of poor households, for the same reason that central city abandonment might lead to long-term reductions.

Stanford professor’s study finds gentrification disproportionately affects minorities. “As neighborhoods gentrify, when poor people can no longer remain in their neighborhoods and move, there are fewer affordable neighborhoods,” Hwang said.

SAN FRANCISCO (KGO) — A new study claims San Francisco and Oakland are the most “intensely gentrified” cities in the United States. The National Community Reinvestment Coalition analyzed data from the U.S. Census Bureau.

Researchers identified 954 gentrifying neighborhoods for the study, mostly in 20 metropolitan cities….The full list:

• San Francisco-Oakland.
• Denver.
• Boston.
• Miami-Fort Lauderdale.
• New Orleans.
• Austin, Texas.
• New York City.
• San Jose, Calif.

Yet, few empirical studies address the transformation of inner-ring suburbs. Gentrification includes physical, social, and economic changes in neighborhoods, but it is arguably most visible through physical reinvestment in the built environment.

Nope, flipping houses isn’t gentrification. Flipping a house involves purchase by an investor of a property to be resold, perhaps with upgrades to the property’s condition or desirability, then turning around and reselling the house to a buyer. The idea is to sell the house quickly and with a substantial profit margin.

The effects of gentrification On the positive side, gentrification often leads to commercial development, improved economic opportunity, lower crime rates, and an increase in property values, which benefits existing homeowners.

Antwan Jones, Assistant Professor of Sociology at George Washington University, explains the critical difference between gentrification and revitalization: “A gentrifying neighborhood will see new, affluent residents who focus on ‘reinvesting resources for greater returns’ – rehabbing houses, for example.” As property …
