Question

The dissolution of caldium chioride in water is very exothormic and is used in Thot compresses" to produce heat. When the inner plastic bag of the compress is broken, the calcium chloride dissolves in the water contained in the outer bag. The reaction is very exothermic and produces the desirnd warming efect. Part C A hypothetical solution forms between a solid and a liquid. The values of the thermodynamic quantities involved in the process are shown in the fo table Action separation of solute separation of solvent Enthalpy 14.5 kJ/mol 22.8 kJ/mol formation of solute-solvent interactions -86.7 kJ/mol solute Calculate the enthalpy of solution in kilojoules per mole of solute. Enter your answer numerically in kilojoules per mole of solute. View Available Hint(s) kJ/mol Submit Provide Feedback Next > MacBook Air

Explanation / Answer

Answer:

The enthalpy of the solution is given by,

(separation of solute) + (separation of solvent) +( Solute-solvent interactions)

(14.5)+(22.8)+(-86.7)

= -49.4KJ/mol

Thanks :)
