NEET Chemistry Ionization Energy MCQ Question

Type: MCQ-numerical-Medium-Class 11

The first ionization enthalpy of an element X in its gaseous state is given as 500 kJ mol⁻¹. Calculate the energy required to remove an electron from 2 moles of gaseous X atoms.

A

1000 kJ

B

500 kJ

C

250 kJ

D

750 kJ

Correct Answer

Option A

Detailed Explanation

Ionization enthalpy is the energy required to remove one mole of electrons from one mole of gaseous atoms. For 2 moles, the energy required is 500 kJ/mol x 2 mol = 1000 kJ.
