Where do i lithium iodide has a lattice energy of −7.3×102kj/mol and a heat of hydration of −793kj/mol. find the heat of solution for lithium iodide. determine how much heat is evolved or absorbed when 10.0g of lithium iodide completely dissolves in water.

For the answer to the answer above, the excess energy must be absorbed to overcome the lattice energy, and then energy is released as the ions are hydrated.

So, the heat of solution =is+7.3X10^2 kJ/mol - 793 kJ/mol =
So the answer is
-63 kJ/mol

I hope you find my answer helpful.
