Challenge Problems
Push your limits with challenges.
Question 1
Calculate the enthalpy of combustion for propane (C₃H₈) given the reaction: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O. Use known enthalpies to find the result.
💡 Hint: Set up the Hess's law equation, balance everything, and remember to input values correctly.
Question 2
A fuel cell's combustion efficiency can be calculated using its standard enthalpy. If a given fuel has a ∆cH° of -2800 kJ/mol and burns 100 moles, what is the total energy released?
💡 Hint: Watch out for unit conversions!
