Question

What is the binding energy of the electron in kJ/mol?

a) 6.242 × 10⁶ kJ/mol
b) 1.602 × 10⁻¹⁹ kJ/mol
c) 9.648 × 10² kJ/mol
d) 1.602 × 10⁻¹⁹ kJ/mol

Answer 1

The binding energy of an electron in an atom is typically measured in electron volts (eV), not kilojoules per mole (kJ/mol). The electron volt is a unit of energy in the International System of Units (SI). The conversion between electron volts and kilojoules per mole is as follows:

1 eV = 1.602 x 10^-19 joules

1 kJ/mol = 96.485 kJ/mol

If you have the binding energy in eV, you can convert it to kJ/mol using the above formula. Please provide the binding energy in eV, and I can help you with the calculation.

To find the binding energy in kJ/mol, you can use the following formula:

Answer 2

The provided options for the electron's binding energy in kJ/mol do not match the typical energy units for such values, and without additional context or calculations, it is not possible to accurately provide the correct answer.

Step-by-step explanation:

The question provided asks for the binding energy of an electron in kilojoules per mole (kJ/mol). To answer this question, we must recall the relationship between energy in electron volts and joules. The conversion factor is 1 eV = 1.602 × 10-19 J. However, none of the given options (a-d) directly provide the answer in the correct unit of kJ/mol for binding energy. Instead, they provide values in different units, like kJ/mol or J, without the necessary conversion.

Since the exact value for the electron's binding energy was anticipated from a calculation not fully detailed here, and without that information or context, it is not possible to accurately select the correct answer. Moreover, none of the answers listed in kJ/mol are the result of an apparent calculation from the provided information. Therefore, I must refrain from selecting one of the given options.
