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.
