Question

Use the following details to calculate the enthalpy of hydration for caesium iodide and caesium hydroxide, respectively: CsI: Lattice energy = +604 kJ/mol, δ H_sol = +33 kJ/mol; CsOH: Lattice energy = +724 kJ/mol, δ H_sol = -72 kJ/mol

Prashant Kotian · Accepted Answer

Correct answer: A. δ H_hydration = δ H_solution - Lattice Energy. CsI: +33 - 604 = -571 kJ/mol. CsOH: -72 - 724 = -796 kJ/mol.
