We can use the following equation to solve for ΔH˚rxn:
Note that we need to multiply each ΔH˚f by the stoichiometric coefficient since ΔH˚f is in kJ/mol.
Also, note that ΔH˚f for elements in their standard state is 0.
What is ΔH°rxn for the following chemical reaction?
CO2(g) + 2 KOH (s) → H2O(g) + K2CO3(s)
You can use the following table of standard heats of formation (ΔH°f) to calculate the enthalpy of the given reaction
Express the standard enthalpy of reaction to three significant figures and include the appropriate units
