A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It works by lowering the activation energy, making it easier for reactants to collide and form products.
A catalyst, such as manganese dioxide, can speed up the decomposition of hydrogen peroxide into water and oxygen gas by providing an alternative reaction pathway with a lower activation energy. This allows the reaction to occur more quickly and efficiently.
No, not all substances can act as a catalyst for the decomposition of hydrogen peroxide. It requires a substance with certain properties, such as a high surface area and the ability to interact with hydrogen peroxide molecules, in order to effectively lower the activation energy and accelerate the reaction.
Hydrogen peroxide can act as a signaling molecule in biological reactions, playing a role in processes such as cell signaling, wound healing, and immune response. It can also be used as a disinfectant to kill harmful bacteria.
Hydrogen peroxide is commonly used as a bleaching agent in the production of paper and textiles. It is also used as a disinfectant, oxidizing agent, and rocket propellant. Additionally, it can be used as a source of oxygen in some industrial processes.
