Part A
Chemical energy is released or absorbed from reactions in
various forms. The most easily measurable form of energy
comes in the form of heat, or enthalpy. The enthalpy of a
reaction can be calculated from the heats of formation of the
Calculate the standard enthalpy change for the reaction
2A +B= 2C+ 2D
substances involved in the reaction:
Use the following data:
Δ,ΗΣ n Δ Η (products) -Ση, Δ; Η' reactants)
where n represents the stoichiometric coefficients.
