Type: MCQ-numerical-Medium-Class 11
The enthalpy change for the following reaction NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l) is –57 kJ. Predict the value of the enthalpy change in the following reaction. Ba(OH)₂ + H₂SO₄(aq) → BaSO₄(s) + 2H₂O(l)
A
–57 kJ
B
–76 kJ
C
–114 kJ
D
–228 kJ
Correct Answer
Option C
Detailed Explanation
The enthalpy change for neutralization reactions is typically –57 kJ/mol of water formed. Since 2 moles of water are formed, the enthalpy change is –114 kJ.
