NEET Chemistry Enthalpy MCQ Question
Type: MCQ-numerical-Easy-Class 11
Calculate the enthalpy change for the reaction where 2 moles of Na(s) are converted into Na(g) using the given enthalpy of atomization.
A
216.8 kJ/mol
B
108.4 kJ/mol
C
435.0 kJ/mol
D
783.0 kJ/mol
Correct Answer
Option A
Detailed Explanation
The enthalpy of atomization for Na(s) to Na(g) is given as 108.4 kJ/mol. For 2 moles, the enthalpy change is 2 x 108.4 kJ/mol = 216.8 kJ/mol.
