Question

Given the following data, calculate the second electron affinity of sulfur. Is the $$S^{2–}$$ more stable as a free ion or in CaS?

Accepted Answer

EA_{2} = 570.8 $$kJ/molS^{2–} is $$more stable in CaS.

Answer

EA_{2} = –365.3 $$kJ/molS^{2–} is $$more stable as a free ion.

Answer

EA_{2} = –134.2 $$kJ/molS^{2–} is $$more stable in CaS.

Answer

EA_{2} = 729.1 $$kJ/molS^{2–} is $$more stable as a free ion.
