NEET Chemistry Ionization Energy MCQ Question
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.
1000 kJ
500 kJ
250 kJ
750 kJ
Correct Answer
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.
