an ic engine burns octane C8H18 and uses 125% theortical air.the air and fuel enter at 25, the product leave at 700k. in the engine 85% of carbon burns to co2 and the remainder burn to co. the heat transfer loss to the cooling jacket is negligible. determine the power output if the engine burns 6kg fuel per hour

INTERACTIVE EXAMPLE Constant Volume Calorimetry Octane, C8H18, a primary constituent of gasoline, burns in air: C8H18(ℓ) + 12 1/2 O2(g) → 8 CO2(g) + 9 H2O(ℓ) A 1.00-g sample of octane is burned in a constant volume calorimeter. The calorimeter is in an insulated container with 1.20 kg of water. The temperature of the water and the bomb rises from 25.00 °C (298.15 K) to 33.21 °C (306.36 K). The heat required to raise the bomb’s temperature (its heat capacity),...

Ethanol (C2H5OH) and gasoline (assumed to be all octane, C8H18) are both used as automobile fuel. If gasoline is selling for $2.25/gal, what would the price of ethanol have to be in order to provide the same amount of heat per dollar? The density and ΔH f of octane are 0.7025 g/mL and −249.9 kJ/mol and the density and ΔH f of ethanol are 0.7894 g/mL and −277.0 kJ/mol, respectively. Assume that the products of combustion are CO2(g) and H2O(l)....
