Question:

a. Define enthalpy change of solution.

b. Given the enthalpy changes ΔH₁ and ΔH₂ below, construct a Hess’s cycle that will enable you to find the enthalpy change, ΔH_r, for the reaction:

MgCl₂(s) + 6H₂O(l) → MgCl₂.6H₂O(s) ΔH_r

MgCl₂(s) + aq → MgCl₂(aq) ΔH₁

MgCl₂.6H₂O(s) + aq → MgCl₂(aq) ΔH₂
