Exercises C. The complete combustion of isooctane at 25 °C may be represented by: C₂H₁() + 2/2 O₂(g) → 8 CO2(g) + 9 H₂O(A) Calculate An when 0.692 g of isooctane (114.23 g/mol) is completely combusted. Hints: Angsgaseous products-gaseous reactants Calculate the number of moles of isooctane. Calculate the number of moles of oxygen that would react with that amount of isooctane, and calculate the number of moles of carbon dioxide that would be produced from that amount of isooctane. Circle your answer. Calculate ART, when 0.692 g of isooctane is completely combusted at 25.0 °C. (This quantity should have units of J, so R-8.3145 J mol K.) Circle your answer. Use eqn 2 to calculate AH when 0.692 g of isooctane is completely combusted at 25 °C. (AE was calculated in Exercise B. Be mindful of units!) Circle your answer. Calculate the heat of combustion of isooctane in kJ/mol at 25 °C. The heat of combustion of a substance is simply a ratio of the change in enthalpy when that substance was combusted to the number of moles of the substance that was combusted (i.e.,AHcombustion AH/n). Circle your answer.
