Question

N/2 of X(g) are converted into X+(g) by energy E1.N/2 atoms of X(g) are converted into X-(g) by energy E2.Hence , ionisation potential and electron affinity of X(g) are
(N=avagardo number)​

Answer 1

Given :

Number of atoms of  X⁺(g) converted by energy E₁ = N/2

Number of atoms of  X⁻g) converted by energy E₂ = N/2

To find :

a) Ionisation potential

b) electron affinity

Solution :

X   ⇒   X⁺(g)   +   e⁻

• a) Ionisation potential (I) = Energy / No of atoms

                                        = E₁ / (N/2)

       Ionisation potential is E₁ / (N/2)

• b)  electron affinity (E) = Energy / No of atoms

                                    = E₂ / (N/2)

      electron affinity is E₂ / (N/2)
