WebIn one definition, the lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. This definition causes the value for the lattice energy to always be positive, since this will always be an endothermic reaction. The other definition says that lattice energy is the reverse process ... WebThe lattice energy values are more in the case of MgBr2 and SrBr2 because of a more positive charge on the ions in comparison to RbBr and NaBr which are +2 and +1 respectively. The lattice energy of RbBr and NaBr is compared to the radius of cations. Na+ and Rb+ both lie in the same group, on moving down the group the atomic radius increases. Web18 dec. 2024 · 2nd ionization energy of Sr (g)=1064 kJ per mol, Enthalpy dissociation energy of I2 (s)= 62.4 kJ per mol, Bond dissociation energy of I2 (g)= 152.55 kJ per mol, 1st electron affinity of I (g)= -295.15 kJ per mol, Lattice energy of SrI2 (s)=-1959.75 kJ per mol.
