NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
Given that the enthalpy of atomization for dihydrogen (H₂) is 435.0 kJ/mol, what would be the enthalpy change when 0.5 moles of H₂ are completely atomized?
A
217.5 kJ
B
435.0 kJ
C
870.0 kJ
D
108.4 kJ
Correct Answer
Option A
Detailed Explanation
The enthalpy of atomization is given per mole, so for 0.5 moles of H₂, the enthalpy change is (435.0 kJ/mol) * 0.5 = 217.5 kJ.
