1.	K+F→K + + F − , Δ H was calculated to be 19 kcal under conditions where the cations and anions were prevented by electrostatic separation from combining with each other. The ionization potential of K is 4.3 eV. What is the electron affinity of F?
Answer» QUESTION:K + F → K⁺ + F⁻ , Δ H was calculated to be 19 kcal/mole under conditions where the ANIONS and cations were prevented by electrostatic separation from combining with each other. The IONIZATION potential of K is 4.3 EV. What is the electron affinity of F?ANSWER:The electron affinity of F = 3.476 eV.GIVEN:K + F → K⁺ + F⁻Δ H was calculated to be 19 kcal/mol.The ionization potential of K is 4.3 eV.TO FIND:The electron affinity of F.EXPLANATION:
