Answer:
a) +640 kJ/mol or +1.06x10⁻¹⁸ J
b) +276 kJ/mol
Explanation:
To dissociate the molecule, the bond must be broken, thus, it's necessary energy equal to the energy of the bond, which can be calculated by:
E = (Q1*Q2)/(4*π*ε*r)
Where Q is the charge of the ions, ε is a constant (8.854x10⁻¹²C²J ⁻¹ m⁻¹), and r is the bond length. Each one of the ions has a charge equal to 1. The elementary charge is 1.602x10⁻¹⁹C, which will be the charge of them.
1 mol has 6.022x10²³ molecules (Avogadros' number), so the energy of 1 mol is the energy of 1 molecule multiplied by it:
E = 6.022x10²³ *(1.602x10⁻¹⁹)²/(4π*8.854x10⁻¹²*2.17x10⁻¹⁰)
E = +640113 J/mol
E = +640 kJ/mol
Or at 1 molecule: E =640/6.022x10²³ = +1.06x10⁻²¹ kJ = +1.06x10⁻¹⁸ J
b) The energy variation to dissociate the molecule at its neutral atoms is the energy of dissociation less the difference of the ionization energy of K and the electron affinity of F (EA):
498 = 640 - (418 - EA)
640 -418 + EA = 498
222 + EA = 498
EA = +276 kJ/mol

For each pair of molecules given in the table below, the correct relationships are identified as follows.
<h3>The relationships between the molecules are given as?</h3>
- These are structural isomers. This is because, they have the same molecular formula (C₆H₁₂) but possess varying structures.
- The given pair of molecules posses similar formula (C₄H₁₀O) and can be superimposed on one another via rotation of the entire molecule, hence they are identical isomers.
- In this case the pair of molecules possess similar molecular formula (C₄H₁₀O) and similar arrangement of atoms. Hence, they are identical isomers.
- This case also features structural isomers. They both contain the same carbon chain with similar formula - C₃H₆BrCl
- These pair as identical isomers. They are also derived from C₃H₆BrCl.
- This pair are called stereoisomers isomers. This is because they contain the same about of molecules but are different in the position of the alcohol (-OH) group. But more importantly, the position of the bonding is the same.
- This set is a functional pair. This is because the composition of the molecules present in each case are different.
- This is also a functional pair.
<h3>What is a molecules?</h3>
