Reciprocating chemical reaction is it possible?

[avolaster]

i've got thoughts about a series of chemical reactions that would simply keep on repeating. perhaps by time release. the thought is to use this perpetual chemical reaction to create a battery that releases the electrons then has a series of chemical reactions eventually resulting in the two original chemicals that have electric potential, once the electrons are released again the chemical process hapens over again. it's a never ending battery, essentailly.


... and it's not like electrons are lost, they are simply un enegrized. please correct me if I am wrong on any detail.

also, is it even possible?

No.

What you've got there is a chemical perpertual motion machine.

It is possible to get chemical reactions to oscillate (there's a common high school experiment that shows this), but it is short-lived. It cannot repeat for long.

You cannot extract energy from it. Even if you could, then as soon as you removed the energy you would stop the reaction.

To echo what DaveC said it is impossible.

Are you aware of the Gibbs' Free Energy concept?

All systems tend toward the lowest energy possible. This is the reason reactions occur spontaneously (they give off energy). Once the reaction has completed, you need to put energy into the system, in one form or another, to get back to the original and have the reaction proceed to produce energy.

Whatever you idea is, this series of reactions, I'm sure that a closer look will reveal steps that require energy input. Thus you are not really creating a never ending battery, more like a rechargeable battery.

Googling oscillating chemical reaction will turn up common demonstrations of said:

What if you had a chemical reaction in the bottom of a piston, reaction occurs, gas released, piston moves upwards, once the reaction is complete the piston starts to move downwards compressing the system using its own weight under the force of gravity. Could the increase in pressure and temperature due to the piston be enough to create another reaction or somehow recombine the products?

No. It goes against first law of thermodynamics. You can't build perpetuum mobile, period.
