Answer to Question #180786 in Physical Chemistry for Sam

Question

Calculate the ^H for the dissolution reaction of salts below using the thermodynamic data given

a)LiCl -408.61kj/mol

b)NaBr -360.0 kJ/mol

Answer 1

= LiCl-408.61/6 ×10^-6

= -68.10167 × 10^-6 J

= NaBr -360/6 × 10^-6

= -60 × 10^-6J
