The combustion of octane in a gasoline engine, responsible for powering a car, is represented below by its equation of reaction.

2 C₈H₁₈ (l) + 25 O₂ (g) →16 CO₂ (g) + 18 H₂O (g)

Do you anticipate entropy to increase in this chemical conversion?

a The entropy will likely remain constant.
b. No, on the contrary, I anticipate entropy to decrease (it uses up a lot of oxygen).
c. It is not possible to conclude based on the equation of reaction.
d. Yes, I anticipate entropy will increase.
