What else can I help you with?
Do most industrial chemical reactions use catalysts?
Yes, most industrial chemical reactions utilize catalysts to enhance reaction rates and improve efficiency. Catalysts lower the activation energy required for reactions, allowing them to occur under milder conditions and reducing energy costs. This is particularly important in large-scale processes, where maximizing yield and minimizing waste are critical for economic viability. Overall, catalysts play a crucial role in increasing production efficiency in the chemical industry.
All chemical breakdown processes in cells directly involved?
Chemical breakdown processes in cells are mainly carried out by enzymes, which catalyze reactions that break down molecules into smaller components. For example, glycolysis breaks down glucose into pyruvate, while the citric acid cycle further breaks down pyruvate into CO2 and ATP. These breakdown processes release energy stored in chemical bonds, which the cell can then use for various cellular activities.
What is the use of catalysts?
A catalyst helps speed up a chemical reaction. For example, a catalyst of acidified dichromate ions or acidified permanganate ions can help speed up the reactions of oxidation of an (alcohol into an aldehyde?) etc. Catalysts are used for reactions which would usually be of a very slow speed.
Is cracking of petroluem fraction a physical or chemical change?
Cracking of petroleum fractions is a chemical change. It involves breaking down larger hydrocarbon molecules into smaller, more valuable ones through the use of heat and catalysts. This process alters the chemical composition of the molecules, resulting in the formation of different products.
What are the roles of enzymes?
Enzymes catalyze reactions by lowering the activation energy needed without themselves being used up in the process. Without catalysts such as enzymes, some chemical metabolic reactions would take forever to happen or not happen at all. a specific enzyme usually catalyzes only one kind of chemical reaction

Is it true or false catalysts speed chemical reactions but are not changed by them?
True. That's one of the reasons you use them.
Why are catalysts usually expensive?
Catalysts are usually expensive due to their specialized chemical composition, which often includes rare or precious metals like platinum, palladium, or rhodium. These metals are costly to mine and refine, contributing to the overall price of the catalyst. Additionally, the manufacturing process for catalysts is complex and requires sophisticated technology, further driving up the cost.
What do organisms use to carry out the chemical activities of life?
Organisms use proteins as catalysts for chemical reactions, enzymes to facilitate reactions, and metabolic pathways to break down and build molecules. These processes require energy in the form of ATP to carry out the chemical activities of life.
Can enzymes be used once?
Enzymes are biological catalysts, and like all catalysts they have the property of affecting some chemical reaction (normally, either speeding it up or slowing it down) without being used up or altered in the process. They can be re-used. Indeed, it is often necessary to use some antagonistic enzyme to halt the action of a given enzyme when it has done enough of what it is supposed to do.

What chemical process links monomers together?
Polymerization is the chemical process that links monomers together to form larger macromolecules called polymers. This process can be initiated by various methods, including heat, radiation, or the use of catalysts.
Use enzymes in a sentence?
"The enzymes were used to cause a specific biochemical reaction on the agent."

Could dilute sulphuric acid be used as catalyst?
There are many chemical processes that use sulfuric acid catalysts - refining petroleum is a big one. Most processes that use it, use very concentrated acid because they want the reaction to go quickly.
