### Potential energy comparison

When is potential energy highest? For example, for combustion, is it highest before or after combustion? Why? Does the book cover this?

### Re: Potential energy comparison

I would say that potential energy is highest before combustion, as it will all be converted to kinetic energy during the reaction.
