Question

Select which process describes the following energy changes. (Ionization energy, electron affinity, bond enthalpy, or standard enthalpy of formation

A. F(g) + e^- => F^-(g)

B. F₂(g) => 2F(g)

C. Na(g) => Na⁺(g) + e^-

D. Na(s) + 1/2F_{2(g) => NaF(g)}

Answer 1

A. F(g) + e^- => F^-(g)---------------------electron affinity

B. F₂(g) => 2F(g)--------------------------------------bond enthalpy

C. Na(g) => Na⁺(g) + e^{---------------------------------ionization enthalpy}

D. Na(s) + 1/2F_{2(g) => NaF(g)}---------------------------------standard enthalpy of formation
