Burning one mole of propane according to the following reaction: C₃H₈(g) + 5 O₂(g) → 3 CO₂ + 4 H₂O
Liberates 526 kcal of energy. If all of the coefficients are tripled, how much energy will be released?

Question

Quizplus · Accepted Answer

Tripling the coefficients of a balanced chemical equation triples the amount of reactants and products involved in the reaction, which in turn triples the energy change associated with the reaction. Therefore, tripling the coefficients in the given reaction would release 3 times 526 kcal, or 1578 kcal.
