NEET Chemistry Ionization Energy MCQ Question
Calculate the ionization enthalpy of atomic hydrogen in kJ mol⁻¹, given that the energy of an electron in the ground state of a hydrogen atom is -2.18×10⁻¹⁸ J.
1312 kJ mol⁻¹
1040 kJ mol⁻¹
1500 kJ mol⁻¹
400 kJ mol⁻¹
Correct Answer
Detailed Explanation
The ionization enthalpy can be calculated by converting the given energy from J to kJ and then using Avogadro's number to find the value per mole. The conversion yields approximately 1312 kJ mol⁻¹.
