Question: a. A flask containing gaseous N2 is irradiated with 25-nm light. Using the following information, indicate what species can form in this flask during irradiation.
a. A flask containing gaseous N2 is irradiated with 25-nm light. Using the following information, indicate what species can form in this flask during irradiation.
N2(g) → 2N(g) ΔH = 941 kJ/ mol
N2(g) → N2+(g) + e- ΔH = 1501 kJ/ mol
N(g) → N+(g) + e- ΔH = 1402 kJ/ mol
b. What range of wavelengths will produce atomic nitro-gen in the flask but will not produce any ions?
c. Explain why the first ionization energy of N2 (1501 kJ/ mol) is greater than the first ionization energy of atomic nitrogen (1402 kJ/ mol).
