The thermochemical equation for the combustion of propane is:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(l)ΔH⊖=−2219 kJ mol−1
Identify the true statements.
- I. If 1.00 g of propane is burnt completely, 2219 kJ of energy are produced.
- II. The reactants have more potential energy than the products.
- III. The reaction is exothermic.
