What are the two important classes of catalysts?
The two important classes of catalysts are homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase from the reactants. Each class has its own advantages and applications depending on the specific reaction and conditions.
Ensymes are usually what?
Enzymes are usually something that reduces a chemical reaction.
What are substances that increases the rate of a chemical reaction?
Catalysts
What are facts about catalysts?
Some of the facts are: 1. Catalysts never get consumed in a reaction 2. Catalysts lower the activation energy of the reaction by providing an alternative path to it. 3. Some catalysts do not take part in reaction. They just provide surface or sites for the reaction to take place.
Substances that hasten chemical reaction time without themselves undergoing changes are called?
catalysts. These substances work by providing an alternative pathway for the reaction to occur more rapidly, lowering the activation energy needed for the reaction to proceed. Catalysts do not undergo permanent changes in their chemical composition during the reaction.
How many types of catalyst are there?
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
How much energy do catalysts need?
Usually none.
What are biological catalysts sensitive to?
Environmental changes. Usually drastic ones.
What ingredients are necessary to make plastic?
Basically oil, usually from petroleum, and polymerizing catalysts.
What class of organic molecules includes biological catalysts?
organic catalysts made of protein are called enzymes (these are usually made by living things)nonprotein based organic catalysts are simply called organic catalysts (these are usually synthesized artificially)
Can inorganic substances catalyze reactions?
Yes, but usually enzymes are the primary catalysts in the Biological world.
One way in which inorganic catalysts and enzymes differ is?
Inorganic catalysts are typically synthetic molecules while enzymes are biological molecules. Enzymes are highly specific to their substrates due to their complex three-dimensional structures, whereas inorganic catalysts are less specific and can catalyze a wider range of reactions. Enzymes are usually more efficient in catalyzing reactions compared to inorganic catalysts.
Are elements able to bond together without enzymes and why?
Enzymes, as used in reactions, usually do not causes bond formation. They are usually responsible for breaking of bonds but when used in bond formation, they are commonly catalysts. Catalysts simply provide a lower activation energy and causes the reaction to occur faster. Thus, without catalysts, the reaction (including bond formation) will still occur, just at a slower rater. Thus, bond formation can definitely occur without enzymes (catalysts).
Why are all enzymes catalysts but not all catalysts are enzymes?
but all catalysts aren't enzymes...
How enzymes and catalysts related?
Enzymes are catalysts.
How are catalysts and enzyme related?
Enzymes are catalysts.
What are some disadvantages of using a cataylst?
Generally, the reasons why catalysts are bad are not to do with the chemistry itself, they are usually practical reasons. For example: catalysts can be expensive (e.g. palladium and platinum), however, because they are reusable and can often be used in tiny amounts this is not a massive issue. Catalysts could be toxic/harmful and therefore make them awkward to handle/use, also if they are toxic/harmful if they are used in a product that will eventually be consumed (etc.) there could be trace amounts in the product if not purified properly.. these are the only two i can think of at the moment, however if i think of more i will update this post.
