Most automobiles function by burning gasoline by a process similar to the equation shown,in which octane is burned. C8H18 + O2 $\rightarrow$ CO2 + H2O + heat (not balanced) Using the concept of entropy,interpret the implications of this reaction.

A) It goes to the right because it is spontaneous after a spark is supplied. B) It explains why a car stops running when there is no gas in the fuel tank. C) Gasoline can be made commercially because the reaction can run backwards if the energy is returned to the CO2 and H2O. D) All of these responses are correct with respect to entropy.
