1.In an experimental cracking of octane (C8H18), the product has the following composition: 19.5% C3H8, 59.4% C4H10, and 21.1% C5H12. Cracking is the process of reacting long hydrocarbon chains with hydrogen gas to produce hydrocarbons of shorter lengths. Determine the molar ratio of hydrogen gas consumed to octane reacted.

Expert Solution

with stoichiometry and mole balance all the values are calculated and 100 percent conversion of octane and hydrogen is assumed.

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), Cbomb, is 837 J/K. The...
