Oxygen is the limiting reactant. Concepts and reason This is based on the concept that the limiting reagent decides how much amount of other reactants will be consumed when the reaction takes place.Octane number, also called octane value or octane rating, is one of the critical measures of a gasoline's performance. It is a measure of a fuel's resistance to knock or to ignite prematurely.

Octane Definition. The meaning of Octane - Word Panda

The short answer is that octane is the measure of how much compression a fuel can withstand before igniting. Or, in layman's terms, the higher the octane rating, the less likely the fuel is going to pre-ignite (read: explode unexpectedly) at higher pressures and damage your engine. That's why performance...Octane is one of the alkane group of hydrocarbons and is a major component of petrol (gasoline). Burning octane gives this chemical reaction: 2.C8H18 + 25.O2 = 16.CO2 + 18.H2O The formula shows that 1 kg of octane burns with 3.51 kg oxygen to produce 3.09 kg shift the reaction to the left.Octane ratings increase in aromatics with same number of carbons. It is important to know octane numbers for petrol because the auto ignition of fuels causes a �knocking� effect in petrol engines. This is where it ignites twice; once due to the high pressure and again when the spark ignites the petrol..208mol of octane is allowed to react with .780 mol of oxygen. Oxygen is the limiting reactant. Subtract that amount from 0.208 moles of octane, and you get 0.208 - [0.708 x (25/2)] = 0.151 moles of octane left. If you need to give the number of grams, multiply that number by the molecular weight of...

Chantel,

You are totally correct that oxygen is the limiting reagent: for every 25 moles of oxygen, you use up two moles of octane. That means for 0.780 moles of oxygen, you use up 0.708 x 2/25 moles of oxygen = 0.0566 moles of octane.

Subtract that amount from 0.208 moles of octane, and you get 0.208 - [0.708 x (25/2)] = 0.151 moles of octane left.

If you need to give the number of grams, multiply that number by the molecular weight of octane, 114.23: 114.23 x 0.151 = 17.3 grams.

Hope this helped!
