For a reaction to be feasible at a given temperature, it must happen spontaneously, which means no extra energy needs to be put in for the reaction to occur. A reaction only occurs spontaneously if the Gibbs free energy change is less than zero (ie ΔG is negative).

Also question is, what is the mean of feasibility?

Definition of feasible. 1 : capable of being done or carried out a feasible plan. 2 : capable of being used or dealt with successfully : suitable.

Secondly, what does spontaneous mean in chemistry? A spontaneous reaction is a reaction that occurs in a given set of conditions without intervention. Spontaneous reactions are accompanied by an increase in overall entropy, or disorder. If the Gibbs Free Energy is negative, then the reaction is spontaneous, and if it is positive, then it is nonspontaneous.

Beside this, what does thermodynamically feasible mean?

Thermodynamical feasible means the overall Gibs free energy of the reaction is negative.

How do you know if a reaction is feasible or not?

Whether or not a reaction (or other physical change) is feasible depends on the sign of ΔG. If ΔG is positive, then the reaction isn't feasible - it can't happen. For a reaction to be feasible, ΔG has to be negative.

What is feasibility study and its types?

Types of Feasibility. Various types of feasibility that are commonly considered include technical feasibility, operational feasibility, and economic feasibility. Operational feasibility assesses the extent to which the required software performs a series of steps to solve business problems and user requirements.

What is an example of a feasibility study?

Feasibility studyexample
A hospital, for example, aiming to expand, i.e., add an extension to the building, may perform a feasibility study. The study will determine whether the project should go ahead. The people carrying out the study will take into account labor and material costs.

What is the synonym of feasible?

feasible, executable, practicable, viable, workable(adj) capable of being done with means at hand and circumstances as they are. Synonyms: workable, viable, practicable, operable, executable.

What do you mean by feasibility study?

An analysis and evaluation of a proposed project to determine if it (1) is technically feasible, (2) is feasible within the estimated cost, and (3) will be profitable. Feasibility studies are almost always conducted where large sums are at stake. Also called feasibility analysis. See also cost benefit analysis.

What is the importance of feasibility study?

Feasibility studies are important to business development. They can allow a business to address where and how it will operate. They can also identify potential obstacles that may impede its operations and recognize the amount of funding it will need to get the business up and running.

What does feasible time mean?

When someone asks "Is it feasible?" the person is asking if you'll be able to get something done. Feasible things are possible. If you have enough time, money, or energy to do something, it's feasible. Something might be feasible at one time and then not feasible at another time.

How do you define enthalpy?

Enthalpy is a thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system. It reflects the capacity to do non-mechanical work and the capacity to release heat. Enthalpy is denoted as H; specific enthalpy denoted as h.

Can entropy be negative?

Entropy is the amount of disorder in a system. Negative entropy means that something is becoming less disordered. In order for something to become less disordered, energy must be used. The second law of thermodynamics states that the world as a whole is always in a state of positive entropy.

What do you mean by free energy?

In physics and physical chemistry, free energy refers to the amount of internal energy of a thermodynamic system that is available to perform work. Helmholtz free energy is energy that may be converted into work at constant temperature and volume.

What is entropy measured in?

The SI unit for Entropy (S) is Joules per Kelvin (J/K). A more positive value of entropy means a reaction is more likely to happen spontaneously.

What is entropy in chemistry?

In chemistry, entropy is represented by the capital letter S, and it is a thermodynamic function that describes the randomness and disorder of molecules based on the number of different arrangements available to them in a given system or reaction.

What is Delta H?

In chemistry, the letter "H" represents the enthalpy of a system. Enthalpy refers to the sum of the internal energy of a system plus the product of the system's pressure and volume. The delta symbol is used to represent change. Therefore, delta H represents the change in enthalpy of a system in a reaction.

What is concept of entropy?

Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

How do I calculate entropy?

Key Takeaways: Calculating Entropy
  1. Entropy is a measure of probability and the molecular disorder of a macroscopic system.
  2. If each configuration is equally probable, then the entropy is the natural logarithm of the number of configurations, multiplied by Boltzmann's constant: S = kB ln W.

What is the standard free energy change?

The standard free energy of a substance represents the free energy change associated with the formation of the substance from the elements in their most stable forms as they exist under standard conditions.
