Textbook 8.113

8.113 Water gas is an inexpensive, low-grade fuel that can be made from coal. (a) Is the production of water gas exothermic or endothermic? The reaction is C+H2O=CO+H2
The solution manual solves it by using standard enthalpy of formation. Can we solve it by using bond enthalpies?
(I tried but the result is different from the answer.)

Using mean bond enthalpies will result in an answer close to that of the answer from enthalpy of formation, but will be different because the bond enthalpy method is less accurate (uses averages).

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
