Enthalpy change, represented by ΔH, is an important concept in thermodynamics and chemistry. It refers to the amount of heat absorbed or released during a chemical reaction or process. Understanding ...

Enthalpy of reaction, also known as heat of reaction, is a crucial concept in the study of chemical reactions. Understanding how to calculate enthalpy provides insights into the energy changes that ...

The lattice enthalpy corresponds to the attractive term in Equation (5), and in the cases with alkali and halogen, the lattice enthalpy has a large negative value, often cancelling I - A.
