In theory, is it possible to reverse a combustion reaction with added energy? If that’s the case, how would a specific reactant like methane be made?

In theory, is it possible to reverse a combustion reaction with added energy? If that’s the case, how would a specific reactant like methane be made?

Answer 1

Theoretically, yes, but you’d need to have a combustion reaction with 100% efficiency and capture 100% of the products of combustion in order to revert everything back, and that’s practically impossible.
