Is cooker burning natural gas irreversible?

Yes, burning natural gas in a cooker is irreversible.

When methane (the main component of natural gas) is burned in the presence of oxygen, it undergoes an oxidation reaction. This reaction produces carbon dioxide (CO2) and water vapor (H2O) as products.

The chemical equation for the combustion of methane is:

CH4 + 2O2 -> CO2 + 2H2O

This reaction is exothermic, meaning that it releases heat energy. This heat energy is what allows a cooker to cook food.

Once the reaction has occurred, the carbon dioxide and water vapor cannot be converted back into methane and oxygen. Therefore, the burning of natural gas is an irreversible process.
