Baking powder (baking soda + some acid salts) will release CO2 (carbon dioxide gas) when placed in water. So, even though, in theory, all reactions are reversible, it is not likely that baking powder in water is reversible once the CO2 gas has formed.
Baking powder is generally considered a reversible reaction in water, as it dissolves and dissociates into its components, allowing it to react chemically when mixed with other ingredients. However, the reaction that occurs when baking powder is heated (producing carbon dioxide gas) is irreversible. Thus, while its dissolution in water is reversible, the subsequent chemical reactions during baking are irreversible.
This is a reversible process.
Irreversible examples: Burning a piece of paper, baking a cake, digesting food, rusting of iron, breaking a glass. Reversible examples: Melting ice into water, boiling water into steam, freezing water into ice, dissolving sugar in water, compressing a gas into a liquid.

The process of a kettle of water boiling to form steam is reversible, as it can be reversed by cooling the steam back into water. This transformation involves a change in state from liquid water to gaseous steam and is driven by the input of heat energy.

No it is always reversible
Irreversible... You could distill a cup of prepared coffee - until all the water boils off, but you would never get back the original coffee powder, or granules.
It is reversible. You can allow the water to evaporate, leaving the salt behind.
Mixing lemon juice and baking soda results in a chemical reaction that produces carbon dioxide gas, water, and sodium citrate. This reaction is irreversible as the original substances are transformed into new substances with different properties.
