Per NCERT §5.5(a), the standard enthalpy of combustion of GLUCOSE (C₆H₁₂O₆) is which?
A−2802 kJ/mol
B+2802 kJ/mol
C−74 kJ/mol
D−180 kJ/mol
Answer & Solution
Correct answer: A. −2802 kJ/mol
Per NCERT §5.5(a), C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O; Δ_c H° = −2802 kJ/mol. Body extracts this energy through metabolism.
