Question

For NaCl, lattice energy = -186 kcal/mol, the solvation
energy of Na+ and Clare -97 and -85 kcal/mole
respectively. Therefore for NaCl (s)
(a) enthalpy of solution is exothermic and magnitude
equal to 4 kcal/mol
(b) enthalpy of solution is exothermic and magnitude
equal to 368 kcal/mol
(c) enthalpy of solution is endothermic and magnitude
equal to 4 kcal/mol
(d) enthalpy of solution is endothermic and magnitude
equal to 368 kcal/mol​

Answer 1

Answer:

c is the correct answer
