Question

Consider the following data for nitrogen: atomic mass 14.00 mol electronegativity 3.04 electron affinity kJ * mol ionization energy 1402 3 mol kJ heat of fusion 0.36 mol You may find additional useful data in the ALEKS Data tab. Does the following reaction absorb or release energy? (1) N2+(3) + N () O release absorb Can't be decided with the data given. Is it possible to calculate the amount of energy absorbed or released by reaction (1) using only the data above? O yes no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (1): kJ/mol Does the following reaction absorb or release energy? O release absorb Can't be decided with the data given. (2) N (?) + N() Is it possible to calculate the amount of energy absorbed or released by reaction (2) using only the data above? yes Ono If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (2): kJ/mol

Answer 1

1. N²⁺ (g) + e -----> N⁺ (g)

It is reverse of 2nd ionization of N, during ionization we have add energy , so during addition of electron to ion energy releases .So, following reaction releases energy. (added electron will interaction with nucleus which is stabilizing force, thus energy is released )

2. No , from given data it is not possible to calculate amount of energy released , as it is related to 2nd ionization energy of N , data for which is not provided.

3. N.A.

4.

N⁺ (g) + e ----->N (g)

It is reverse of 1st ionization of N, during ionization we have add energy , so during addition of electron to ion energy releases .So, following reaction releases energy.

(added electron will interaction with nucleus which is stabilizing force, thus energy is released )

5. Yes , from given data it is possible to calculate amount of energy released , as released energy is equal to 1st ionization energy of N , data for which is provided.

6. 1402.3 kJ/mol
