Question

If you are given Avogadro's number of atoms of a gas 'X'. If half of the atoms are converted into X+(g)
by energy AH. The IE of X per mole is
(1)2ΔH
(2) 2ΔH/NA
(3)ΔΗ
(4)ΔΗ/NA​

Answer 1

Answer:

please follow me

Explanation:

Given no. of atoms = Avogadro's no. of atoms = N

A

=6.023×10

23

Given that

2

N

A

atoms are ionized, i.e.,

Ionization energy of

2

N

A

atoms of gas X = ΔH

∴ Ionization energy of 1 atom of gas X =

(

2

N

A

)

ΔH

=

N

A

2.ΔH

Hence, Ionisation energy of gas X is

N

A

2.ΔH
