Homework Help: chemistry URGENT...30 min left

Gasoline is a mixture of hydrocarbons of various chain lengths, ranging from 5-carbon chains to 10-carbon chains. One of the hydrocarbons we often hear about is the 8-carbon chain, octane. Octane combusts with oxygen as given by the balanced equation:

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

Recall that you cannot infer the reaction pathway from the balanced equation. It must be derived experimentally. Yet upon reading this balanced equation, it appears unlikely that the combustion of octane occurs in a single step. Why?
