Question 10 Calculate the lattice energy of RbF (s) using the following thermodynamic data (all data is in kJ/mol). Note that the data given has been perturbed, so looking up theanswer is probably not a good idea.Rb(s) AHsublimation = 64. kJ/molRb(g) IE=577. kJ/molF-F(g) D=442, kJ/molF(g) EA =-187. kJ/molRbF(s) AH°f=-798. kJ/molkJ/mol

To calculate the lattice energy of RbF (s) using the given thermodynamic data, we'll apply Hess's…
