Using Heats of Formation

One of the applications of Hess' Law is the use of heats of formation to determine reaction enthalpies. This page provides exercises in that area. When "New Problem" is pressed, a reaction and a table of heats of formation will be displayed. Use the data provided to determine the enthalpy for the reaction. Enter it in the answer cell and press "Check Answer". Results are displayed in the table.
