The heat released when the requisite amount of ions in the gaseous state combine to give 1 mol of crystal lattice is known as:
Open in App
Solution
The correct option is B lattice energy
The lattice energy of a crystalline solid is usually defined as the energy of formation of the crystal from infinitely-separated ions, molecules, or atoms.
The heat energy released when new bonds are made between the ions and water molecules is known as the hydration enthalpy.
The standard enthalpy of formation of a compound is the change of enthalpy from the formation of 1 mole of the compound from its constituent elements.
Hence, option A is the right answer.
