The lattice energy of KBr is 671.0 kJ/mol and its heat of solution is 19.9 kJ/mol. Calculate the hydration of energy of KBr(s).

Respuesta :

We are given with
Lattice energy = 671.0 kJ/mol
Heat of solution = 19.9 kJ/mol

Heat of hydration = lattice energy + heat of solution
Heat of hydration = 
671.0 kJ/mol + 19.9 kJ/mol
Heat of hydration = 690.9 kJ/mol
