A driven reaction is a chemical reaction that proceeds spontaneously in a particular direction due to either an exergonic change in free energy or the consumption of one or more high-energy molecules. This results in the reaction being thermodynamically favorable and proceeding without the need for external energy input.

What type of chemical reaction produces smaller compounds?
A decomposition reaction produces smaller compounds by breaking down a single reactant into multiple smaller products. This type of reaction is typically driven by heat, light, electricity, or a catalyst.
In volta's battery a chemical reaction between which two metals produced a current?
In Volta's battery, the chemical reaction occurs between zinc and copper, which produces a current through the flow of electrons from the zinc to the copper electrode. This reaction is driven by the difference in electronegativity between the two metals.
What has to be strong in order to cause a chemical reaction to take place?
Chemical reactions are driven by the amount of energy used to break the bonds in the reactants ( the activation energy) and the energy released by making new bonds in the products. The stronger the forces holding together the molecules of products, the more readily the reaction takes place. The difference between the energy produced in making the bonds and breaking the bonds is called ENTHALPY. The reaction can also be driven if the products have a greater degree of disorder (ENTROPY) than the reactants.
What is reactive violence?
Reactive violence occurs in response to a perceived threat or provocation. It is often unplanned and driven by emotions such as anger or fear, resulting in a quick and impulsive reaction.
Is movement an exergonic reaction?
Movement is not considered an exergonic reaction. Exergonic reactions typically refer to chemical reactions that release energy, while movement in living organisms is driven by processes such as muscle contraction and nerve impulses rather than by a specific chemical reaction.
How do you know if a reaction is entropy driven enthalpy driven or driven by both enthalpy and energy?
If the ∆H is positive and the ∆S is positive, then the reaction is entropy driven. If the ∆H is negative and the ∆S is negative, then the reaction is enthalpy driven. If ∆H is positive and ∆S is negative, then the reaction is driven by neither of these. If ∆H is negative and ∆S is positive, then the reaction is driven by both of these.
What type of chemical reaction produces smaller compounds?
A decomposition reaction produces smaller compounds by breaking down a single reactant into multiple smaller products. This type of reaction is typically driven by heat, light, electricity, or a catalyst.
An endergonic reaction that is driven by the splitting of ATP molecules?
In an endergonic reaction, the overall energy change is positive, requiring input of energy. By breaking down ATP molecules, which release energy, the energy released can drive the endergonic reaction forward. This coupling of the endergonic reaction with the exergonic ATP hydrolysis allows the endergonic reaction to proceed.
What does the term spontaneous mean in a chemical reaction?
Spontaneous in a chemical reaction means that the reaction occurs naturally without any external influence once started. It is driven by the inherent properties of the reactants and products, leading to a decrease in free energy and an increase in entropy.
How direction of a reaction can be predicted?
The direction of a chemical reaction can be predicted by comparing the relative energy levels of the reactants and products. If the products are at a lower energy state than the reactants, the reaction is likely to proceed in the forward direction. Additionally, the reaction can be driven by factors such as temperature, pressure, and the concentrations of reactants and products.
What is a chemical reaction in which one element replaces another in a compound or in which two elements in different compounds trade places?
It is called a "Replacement" Reaction.
What is the source of oxygen gas released by a photo system?
The oxygen produced in photosynthesis is derived from the carbon dioxide the organism combines with water. The chemical reaction is driven by energy derived from light. The products of the reaction are oxygen and sugar, and the reaction isn't too difficult to understand. It looks like this:6CO2 + 6H2O → C6H12O6 + 6O2The carbon dioxide and water will, driven by the energy of light, chemically react to form sugar and oxygen.
Is the condensation of ADP and Pi to make ATP an endergonic or an exergonic reaction?
The condensation of ADP and Pi to make ATP is an endergonic reaction because it requires energy input. This process is driven by energy from cellular respiration or photosynthesis.
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
What reaction has occurred when potassium chloride and silver acetate react to produce silver chloride and potassium acetate?
A double displacement reaction has occurred. The potassium and silver ions have swapped partners to form silver chloride and potassium acetate, respectively. This reaction is driven by the exchange of ions between the compounds.
In volta's battery a chemical reaction between which two metals produced a current?
In Volta's battery, the chemical reaction occurs between zinc and copper, which produces a current through the flow of electrons from the zinc to the copper electrode. This reaction is driven by the difference in electronegativity between the two metals.
What is the reaction force when a hammer hits a nail?
The reaction force when a hammer hits a nail is called the law of motion. This motion falls under Newton's Third Law.
