Rbcl lattice enthalpy
WebAnswer (1 of 3): Lattice energies depend on ionic size, charge and arrangement in the solid. Coulomb’s law applies to the electrostatic force associated with the charges. The force is directly proportional to the charge and inversely proportional to the square of the distance between the charges....

• Rubidium chloride is used as a gasoline additive to improve its octane number. • Rubidium chloride has been shown to modify coupling between circadian oscillators via reduced photaic input to the suprachiasmatic nuclei. The outcome is a more equalized circadian rhythm, even for stressed organisms.
