ΔE

Definition

ΔE represents the change in energy of a system during a chemical reaction. It indicates whether energy is being released (negative value) or absorbed (positive value) by the system.

Enthalpy (H): Enthalpy is another term used to describe the amount of energy within a chemical system at constant pressure.

Exothermic Reaction:

An exothermic reaction releases heat into its surroundings, resulting in a negative value for ΔE.

Endothermic Reaction:

An endothermic reaction absorbs heat from its surroundings, leading to a positive value for ΔE.
