This is known as a coupled reaction, where the energy released from an exergonic reaction drives an endergonic reaction by transferring energy.
Endothermic reactions absorb heat energy from the surroundings. To calculate the energy change in an endothermic reaction, you subtract the initial energy of the reactants from the final energy of the products. The resulting positive value indicates that the reaction absorbed energy.
Energy is released during an exothermic reaction. The energy released was enthalpy. This includes quantities such as the attraction between molecules, the lattice energy, the chemical bonds... depends on the reaction.An endothermic reaction absorbs energy in the enthalpy of solution. It comes from the surroundings.
Fusion, in the context of freezing, refers to the process of a substance transitioning from a liquid to a solid state. During this phase change, energy is released into the surroundings, which is an exothermic reaction, not endothermic. To calculate the energy released when a mass of liquid freezes, you can use the formula ( Q = m \times L_f ), where ( Q ) is the heat released, ( m ) is the mass of the liquid, and ( L_f ) is the latent heat of fusion for the substance. This calculation quantifies the energy transferred as the liquid solidifies.
energy released by the reaction or energy absorbed.
To calculate the reaction enthalpy, you subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the heat energy released or absorbed during the reaction.
A reaction that releases energy is usually termed exothermic reaction. Energy is usually released as heat.
Bond energy can be used to calculate the enthalpy change in a chemical reaction by comparing the total energy needed to break the bonds in the reactants with the total energy released when new bonds form in the products. The difference between these two values represents the enthalpy change of the reaction.
The energy for an endergonic reaction can come from an exergonic reaction, where energy is released. This released energy is then used to drive the endergonic reaction forward.
The q value formula is used to calculate the energy released or absorbed in a nuclear reaction. It is calculated by subtracting the total mass of the reactants from the total mass of the products, and then multiplying the difference by the speed of light squared (c2).
In an exothermic reaction heat energy is released.

This is known as a coupled reaction, where the energy released from an exergonic reaction drives an endergonic reaction by transferring energy.
To calculate the amount of energy produced in a nuclear reaction, you need to know the type of reaction (fission or fusion) and the mass difference between the reactants and products. This mass difference can be used in Einstein's famous equation, E=mc^2, to determine the energy released during the reaction. Additionally, the binding energy per nucleon of the nuclei involved is also crucial in estimating the energy output of a nuclear reaction.
The variable that is not required to calculate the Gibbs free-energy change for a chemical reaction is the temperature.
When energy is released during a reaction, it is considered an exothermic reaction. This means that the reaction is giving off heat to the surroundings.
