How many moles of isooctane must be burned to produce 100 kj of heat under standard state conditions? show all of your work.

According to Prosen and Rossini, 1945, the standard heat of combustion of isooctane is -5461.3 kJ/mol. The negative sign is just to depict that there was a release of energy. Thus, to produce 100 kJ energy,

100 kJ ÷ 5461.3 kJ/mol isooctane = 0.0183 moles isooctane.

0.0183 moles of isooctane must be burned.

I hope I was able to answer your question J

Explanation:

Hi, to calculate the moles needed for that energy requirement, first you need to understand the combustion reaction:

Now, you need the heat of reaction. You can either search for it in tables or calculate it from the heats of formation.

For isooctane:

The last step is just a simple calculation:

the movie was based there, and all the animals and characters are native.
