Answer:
19.488 kJ
Explanation:
The overall reaction mechanism shows the reaction between LiCl and H₂O
-------- (1)
-------- (2)
--------- (3)
---------- (4)
The overall reaction =
The heat effects of the above reactions from 1-4 respectively are in the order ; 11311.34 kJ, -857.49 kJ, -873.61 kJ and 439.288kJ respectively
The overall enthalpy change is:
at constant pressure;
Thus; Q = 1311.3 (kJ) 857.49 (kJ) -873.61 (kJ) + 439.288 (kJ)
Q = 19.488 kJ
Thus, the heat effect = 19.488 kJ after the addition of 1 mol of LiCl⋅3H2O(s)
