Question

The lattice energy of CuCl_{2}(s) is 2824 kJ/mol. Use the Born-Haber cycle to determine the ΔH°_{f} for CuCl_{2}(s) from its elements. Compare this with the ΔH°_{f} for CuCl(s) (–137.2 kJ/mol) and determine which compound is more stable.

Accepted Answer

ΔH°_{f} of CuCl_{2}(s) = –237.8 kJ/mol; CuCl_{2}(s) is more stable.

Answer

ΔH°_{f} of CuCl_{2}(s) = 139.1 kJ/mol; CuCl(s) is more stable.

Answer

ΔH°_{f} of CuCl_{2}(s) = –195.7 kJ/mol; CuCl_{2}(s) is more stable.

Answer

ΔH°_{f} of CuCl_{2}(s) = 103.2 kJ/mol; CuCl(s) is more stable.

The lattice energy of CuCl2(s) is 2824 kJ/mol. Use the Born-Haber cycle to determine the ΔH°f for CuCl2(s) from its elements. Compare this with the ΔH°f for CuCl(s) (–137.2 kJ/mol) and determine which compound is more stable.

The lattice energy of CuCl₂(s) is 2824 kJ/mol. Use the Born-Haber cycle to determine the ΔH°_f for CuCl₂(s) from its elements. Compare this with the ΔH°_f for CuCl(s) (–137.2 kJ/mol) and determine which compound is more stable.
