Define the term enthalpy of lattice formation
WebJan 30, 2024 · The enthalpy change of solution refers to the amount of heat that is released or absorbed during the dissolving process (at constant pressure). This enthalpy of solution ( ΔHsolution) can either be positive (endothermic) or negative (exothermic). WebThe Born–Haber cycle is a method of analysing reaction energy. Two German scientists Fritz Haber and Max Born developed it in the year 1919 and it was therefore named after them. It explains and helps in …
