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.
- All heats are in KJ
- Enter only the number in the answer cell. Do not try to enter dimensions. Pay close attention to the signs
- If you press "Show Answer", the solution will be displayed and you will no longer be able to submit an answer to that problem
- This is a brand new page, so bug reports are most welcome.
