Answer #1

The burning (combustion) of gas (octane gas) inside the engine produce gaseous products and energy in the for heat

2C8H18 (g) + 25O2 (g) --------> 16CO2 (g) + 18H2O(g)

The common gases produced are CO2 and H2O.

27 moles of gas are consumed and 34 moles are produced. As a result the pressure increases. The temperature of the gas also increases due to the heat released. The CO2 and H2O are both IR active gases i.e, absorb IR radiations. This leads to global warming.

Consider an internal combustion engine like that used in automobiles. The most common fuel used here is gasoline which is a mixture of hydrocarbons, and an octane rating is given for standardization. Therefore, we will approximate gasoline as being composed of the hydro- carbon, octane, C8H18. Another fuel that is common in racing applications is nitromethane, CH3NO2, used in top fuel dragsters. Let’s consider the combustion of each fuel with oxygen in an internal combustion engine. Let the 8-cylinder engine...
