We’re being asked to determine the standard enthalpy change of formation (ΔH˚f) for acetone. Recall that ΔH˚rxn can be calculated from the enthalpy of formation (ΔH˚f) of the reactants and products involved:
where: n and m are the coefficients of the balanced reaction.
The chemical equation for that reaction is:
Make sure that the reaction is balanced:
H 2 2
F 2 2
Calculate the enthalpy change (ΔH) for the following reaction:
