Worked Solution & Example Answer:The thermochemical equation for the complete combustion of glucose is A - VCE - SSCE Chemistry - Question 2 - 2019 - Paper 1
Step 1
Identify the correct thermochemical equation for glucose combustion
Answer
The correct thermochemical equation for the complete combustion of glucose is:
A. C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
With a ΔH of -2860 kJ mol⁻¹. The complete combustion of glucose yields carbon dioxide and water, releasing a significant amount of energy, which is indicated by the negative enthalpy change.
