Chapter 11, Problem 2RQ
Using KF as an example, write equations that refer to ∆Hsoln and ∆Hhyd· Lattice energy was defined in Chapter 3 as ∆H for the reaction K+(g) + F− (g) → KF(s). Show how you would utilize Hess’s law to calculate ∆Hso1n from ∆Hhyd and ∆HLE for KF, where ∆HLE = lattice energy. ∆Hsoln for KF, as for other soluble ionic compounds, is a relatively small number. How can this be since ∆Hhyd and ∆HLE are relatively large negative numbers?
