In a chemical reaction the reactants contain 385 kJ of chemical energy and the products contain 366 kJ of chemical energy?
In this chemical reaction, the reactants have 385 kJ of chemical energy, while the products have only 366 kJ. This indicates that the reaction is exothermic, as it releases energy in the form of heat, resulting in a net loss of 19 kJ of energy. The difference represents the energy released to the surroundings during the reaction.
Does a catabolic reaction absorb or require energy?
A reaction is endergonic when it requires a net input of energy; if the products contain more energy than the reactants. So, no an endergonic reaction takes in energy. An exergonic reaction releases energy. In an exergonic reaction, the reactants contain more energy than the products.
What is an excothermic change?
An exothermic change is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature. This type of reaction gives off energy in the form of heat as the reactants are converted to products. Examples include combustion reactions and many types of oxidation reactions.
What changes in an exothermic chemical change?
In an exothermic chemical reaction, heat is released to the surroundings. This results in an increase in temperature, which can be observed as a rise in temperature of the surroundings. Additionally, the products of the reaction typically have lower energy than the reactants.
Does anybody know the formula for endothermic reaction and exothermic reaction?
An endothermic reaction absorbs heat from its surroundings, while an exothermic reaction releases heat to its surroundings. The general formula for an endothermic reaction is: reactants + heat → products, and for an exothermic reaction: reactants → products + heat.
What conditions make a chemical reaction energetically favorable?
Chemical reactions are energetically favorable when the products have lower energy than the reactants. This can happen when the reaction releases heat or when the products are more stable than the reactants.

What is the difference between the enthalpy of the products and the enthalpy of the reactants in a chemical reaction?
The difference between the enthalpy of the products and the enthalpy of the reactants in a chemical reaction is known as the change in enthalpy, or H. This value represents the amount of heat energy either absorbed or released during the reaction. If H is positive, the reaction is endothermic and absorbs heat. If H is negative, the reaction is exothermic and releases heat.
Chemical changes release energy?
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
What defines an exothermic reaction?
A reaction that produces heat
What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).
What defines an exotgeic reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that the products have lower energy than the reactants. Exothermic reactions are often characterized by temperature increases, light emission, or sound production.
What is energy of reaction?
Energy and Heat of a reaction is the net amount of energy released or absorbed when the reaction is 100% complete
What makes chemical reaction spontaneous?
A chemical reaction is spontaneous if it releases energy in the form of heat or light, or if it increases the disorder (entropy) of the system. This can happen when the products of the reaction are more stable or have lower energy than the reactants. The key factor is whether the reaction can proceed with a net decrease in free energy.
What ingredients make a chemical reaction?
Chemical reactions occur when two or more substances (reactants) interact to form new substances (products). Key factors that influence chemical reactions include reactant concentration, temperature, surface area, and the presence of a catalyst. The breaking and forming of chemical bonds between atoms in the reactants is what drives the reaction, resulting in the creation of different molecules or compounds.
Can an enzyme be use over again?
Yes they can. Once the chemical reaction has taken place, and the product is formed, the enzyme releases them and combine with other reactants to undergo another chemical reaction.
Does a catabolic reaction absorb or require energy?
A reaction is endergonic when it requires a net input of energy; if the products contain more energy than the reactants. So, no an endergonic reaction takes in energy. An exergonic reaction releases energy. In an exergonic reaction, the reactants contain more energy than the products.
