Question

Define standard enthalpy of formation of a reaction. Write the reaction for the standard enthalpy of formation of C6H12O6

Answer 1

The standard enthalpy of formation is the change in enthalpy that accompanies the formation of one mole of the compound from its elements. The standard enthalpy of reaction occurs in a system when one mole of matter is transformed by a chemical reaction.

C₆H₁₂O₆(s) + 6O₂(g) --> 6CO₂(g) + 6H₂O(g). ∆H=–1273.3 kJ/mol.
